(40 points)Text 1In the 2006 film version of The Devil Wears Prada ,Miranda Priestly, played by Meryl Streep, scolds her unattractive assistant for imagining that high fashion doesn’t affect her, Priestly explains how the deep blue color of the assistant’s sweater descended over the years from fashion shows to departments stores and to the bargain bin in which the poor girl doubtless found her garment.This top-down conception of the fashion business couldn`t be more out of date or at odds with the feverish would described in Overdressed, Elizabeth Cline`s three-year indictment of “fast fashion”. In the last decade or so, advances in technology have allowed mass-market labels such as Zara, H&M, and Uniqlo to react to trends more quickly and anticipate demand more precisely. Quicker turnarounds mean less wasted inventory, more frequent release, and more profit. These labels encourage style-conscious consumers to see clothes as disposable-meant to last only a wash or two, although they don’t advertise that –and to renew their wardrobe every few weeks. By offering on-trend items at dirt-cheap prices, Cline argues, these brands have hijacked fashion cycles, shaking an industry long accustomed to a seasonal pace.The victims of this revolution, of course, are not limited to designers. For H&M to offer a $5.95 knit miniskirt in all its 2,300-pius stores around the world, it must rely on low-wage overseas labor, order in volumes that strain natural resources, and use massive amounts of harmful chemicals.Overdressed is the fashion world`s answer to consumer-activist bestsellers like Michael Pollan`s. The Omnivore`s Dilemma. “Mass-produced clothing ,like fast food, fills a hunger and need, yet is non-durable and wasteful,”Cline argues. Americans, she finds, buy roughly 20 billion garments a year – about 64 items per person – and no matter how much they give away, this excess leads to waste.Towards the end of Overdressed, Cline introduced her ideal, a Brooklyn woman named Sarah Kate Beaumont, who since 2008 has made all of her own clothes –and beautifully. But as Cline is the first to note, it took Beaumont decades to perfect her craft; he r example can’t be knocked off.Though several fast-fashion companies have made efforts to curb their impact on labor and the environment –including H&M, with its green Conscious Collection line –Cline believes lasting change can only be effected by the customer. She exhibits the idealism common to many advocates of sustainability, be it in food or in energy. Vanity is a constant; people will only start shopping more sustainably when they can’t afford not to.21. Priestly criticizes her assistant for her[A] poor bargaining skill.[B] insensitivity to fashion.[C] obsession with high fashion.[D] lack of imagination.22. According to Cline, mass-market labels urge consumers to[A] combat unnecessary waste.[B] shut out the feverish fashion world.[C] resist the influence of advertisements.[D] shop for their garments more frequently.23. The word “indictment”(Line 3, Para.2) is closest in meaning to[A] accusation.[B] enthusiasm.[C] indifference.[D] tolerance.24. Which of the following can be inferred from the last paragraph?[A] Vanity has more often been found in idealists.[B] The fast-fashion industry ignores sustainability.[C] People are more interested in unaffordable garments.[D] Pricing is vital to environment-friendly purchasing.25. What is the subject of the text?[A] Satire on an extravagant lifestyle.[B] Challenge to a high-fashion myth.[C] Criticism of the fast-fashion industry.[D] Exposure of a mass-market secret.Text 2An old saying has it that half of all advertising budgets are wasted-the trouble is, no one knows which half. In the internet age, at least in theory, this fraction can be much reduced. By watching what people search for, click on and say online, compani es can aim “behavioral” ads at those most likely to buy.In the past couple of weeks a quarrel has illustrated the value to advertisers of such fine-grained information: Should advertisers assume that people are happy to be tracked and sent behavioral ads? Or should they have explicit permission?In December 2010 America's Federal Trade Commission (FTC) proposed adding a "do not track "(DNT) option to internet browsers ,so that users could tell advertisers that they did not want to be followed .Microsoft's Internet Explorer and Apple's Safari both offer DNT ;Google's Chrome is due to do so this year. In February the FTC and Digital Advertising Alliance (DAA) agreed that the industry would get cracking on responding to DNT requests.On May 31st Microsoft Set off the row: It said that Internet Explorer 10, the version due to appear windows 8, would have DNT as a default.It is not yet clear how advertisers will respond. Getting a DNT signal does not oblige anyone to stop tracking, although some companies have promised to do so. Unable to tell whether someone really objects to behavioral ads or whether they are sticking w ith Microsoft’s default, some may ignore a DNT signal and press on anyway.Also unclear is why Microsoft has gone it alone. After all, it has an ad business too, which it says will comply with DNT requests, though it is still working out how. If it is trying to upset Google, which relies almost wholly on default will become the norm. DNT does not seem an obviously huge selling point for windows 8-though the firm has compared some of its other products favorably with Google's on that count before. Brendon Lynch, MMicrosoft's chief privacy officer, blogged: "we believe consumers should have more control." Could it really be that simple?26. It is suggested in paragraph 1 that “behavioral”ads help advertisers to:[A] ease competition among themselves[B] lower their operational costs[C] avoid complaints from consumers[D] provide better online services27. “The industry”(Line 6,Para.3) refers to:[A] online advertisers[B] e-commerce conductors[C] digital information analysis[D] internet browser developers28. Bob Liodice holds that setting DNT as a default[A] many cut the number of junk ads[B] fails to affect the ad industry[C] will not benefit consumers[D] goes against human nature29. which of the following is true according to Paragraph.6?[A] DNT may not serve its intended purpose[B] Advertisers are willing to implement DNT[C] DNT is losing its popularity among consumers[D] Advertisers are obliged to offer behavioral ads30. The author's attitude towards what Brendon Lynch said in his blog is one of:[A] indulgence[B] understanding[C] appreciation[D] skepticismText 3Up until a few decades ago, our visions of the future were largely - though by no means uniformly - glowingly positive. Science and technology would cure all the ills of humanity, leading tolives of fulfillment and opportunity for all.Now utopia has grown unfashionable, as we have gained a deeper appreciation of the range of threats facing us, from asteroid strike to epidemic flu and to climate change. You might even be tempted to assume that humanity has little future to look forward to.But such gloominess is misplaced. The fossil record shows that many species have endured for millions of years - so why shouldn't we? Take a broader look at our species' place in the universe, and it becomes clear that we have an excellent chance of surviving for tens, if not hundreds, of thousands of years . Look up Homo sapiens in the "Red List" of threatened species of the International Union for the Conversation of Nature (IUCN) ,and you will read: "Listed as Least Concern as the species is very widely distributed, adaptable, currently increasing, and there are no major threats resulting in an overall population decline."So what does our deep future hold? A growing number of researchers and organizations are now thinking seriously about that question. For example, the Long Now Foundation has its flagship project a medical clock that is designed to still be marking time thousands of years hence.Perhaps willfully, it may be easier to think about such lengthy timescales than about the more immediate future. The potential evolution of today's technology, and its social consequences, is dazzlingly complicated, and it's perhaps best left to science fiction writers and futurologists to explore the many possibilities we can envisage. That's one reason why we have launched Arc, a new publication dedicated to the near future.But take a longer view and there is a surprising amount that we can say with considerable assurance. As so often, the past holds the key to the future: we have now identified enough of the long-term patterns shaping the history of the planet, and our species, to make evidence-based forecasts about the situations in which our descendants will find themselves.This long perspective makes the pessimistic view of our prospects seem more likely to be a passing fad. To be sure, the future is not all rosy. But we are now knowledgeable enough to reduce many of the risks that threatened the existence of earlier humans, and to improve the lot of those to come.31. Our vision of the future used to be inspired by[A] our desire for lives of fulfillment[B] our faith in science and technology[C] our awareness of potential risks[D] our belief in equal opportunity32. The IUCN`s “Red List”suggest that human being are[A] a sustained species[B] a threaten to the environment[C] the world`s dominant power[D] a misplaced race33. Which of the following is true according to Paragraph 5?[A] Arc helps limit the scope of futurological studies.[B] Technology offers solutions to social problem.[C] The interest in science fiction is on the rise.[D] Our Immediate future is hard to conceive.34. To ensure the future of mankind, it is crucial to[A] explore our planet`s abundant resources[B] adopt an optimistic view of the world[C] draw on our experience from the past[D] curb our ambition to reshape history35. Which of the following would be the best title for the text?[A] Uncertainty about Our Future[B] Evolution of the Human Species[C] The Ever-bright Prospects of Mankind[D] Science, Technology and HumanityText 4On a five to three vote, the Supreme Court knocked out much of Arizona's immigration law Monday-a modest policy victory for the Obama Administration. But on the more important matter of the Constitution, the decision was an 8-0 defeat for the federal government and the states.In Arizona, United States, the majority overturned three of the four contested provisions of Arizona's controversial plan to have state and local police enforce federal immigrations law. The Constitutional principles that Washington alone has the power to "establish a uniform Rule of naturalization" and that federal laws precede state laws are noncontroversial. Arizona had attempted to fashion state police that ran to the existing federal ones.Justice Anthony Kennedy, joined by Chief Justice John Roberts and the Court's liberals, ruled that the state flew too close to the federal sun. On the overturned provisions the majority held the congress had deliberately "occupied the field" and Arizona had thus intruded on the federal's privileged powersHowever, the Justices said that Arizona police would be allowed to verify the legal status of people who come in contact with law enforcement. That`s because Congress has always envisioned joint federal-state immigration enforcement and explicitly encourages state officers to share information and cooperate with federal colleagues.Two of the three objecting Justice-Samuel Alito and Clarence Thomas-agreed with this Constitutional logic but disagreed about which Arizona rules conflicted with the federal statute. The only major objection came from Justice Antonin Scalia, who offered an even more robust defense of state privileges going back to the alien and Sedition Acts.The 8-0 objection to President Obama turns on what Justice Samuel Alito describes in his objection as “a shocking assertion of federal executive power”. The White House argued the Arizona`s laws conflicted with its enforcement priorities, even if state laws complied with federal statutes to the letter. In effect, the White House claimed that it could invalidate any otherwise legitimate state law that it disagrees with.Some powers do belong exclusively to the federal government, and control of citizenship and the borders is among them. But if Congress wanted to prevent states from using their own resources to check immigration status. It never did so. The administration was in essence asserting that because it didn't want to carry out Congress's immigration wishes, no state should be allowed to do so either. Every Justice rightly rejected this remarkable claim.36. Three provisions of Arizona`s plan were overturned because they[A] deprived the federal police of Constitutional powers.[B] disturbed the power balance between different states.[C] overstepped the authority of federal immigration law.[D] contradicted both the federal and state policies.37. On which of the following did the Justices agree, according to Paragraph4?[A] Federal officers` duty to withhold immigrants` information.[B] States` independence from federal immigration law.[C] States` legitimate role in immigration enforcement.[D] Congress`s intervention in immigration enforcement.38. It can be inferred from Paragraph 5 that the Alien and Sedition Acts[A] violated the Constitution.[B] undermined the states` interests.[C] supported the federal statute.[D] stood in favor of the states.39. The White House claims that its power of enforcement[A] Outweighs that held by the states.[B] is dependent on the states` support.[C] is established by federal statutes.[D] rarely goes against state laws.40. What can be learned from the last paragraph?[A] Immigration issues are usually decided by Congress.[B] Justices intended to check the power of the Administration.[C] Justices wanted to strengthen its coordination with Congress.[D] The Administration is dominant over immigration issues.Part BDirections:In the following text, some sentences have been removed.

Mark your answers on ANSWER SHEET1.(10 points)The social sciences are flourishing. As of 2005, there were almost half a million professional socialscientists from all fields in the world, working both inside and outside academia. According to the World Social Science Report 2010, the number of social-science students worldwide has swollen by about 11% every year since 2000.Yet this enormous resource in not contributing enough to today`s global challenges including climate change, security, sustainable development and health.(41)______Humanity has the necessary agro-technological tools to eradicate hunger , from genetically engineered crops to artificial fertilizers . Here, too, the problems are social: the organization and distribution of food, wealth and prosperity.(42)____This is a shame—the community should be grasping the opportunity to raise its influence in the real world. To paraphrase the great social scientist Joseph Schumpeter: there is no radical innovation without creative destruction.Today, the social sciences are largely focused on disciplinary problems and internal scholarly debates, rather than on topics with external impact.Analyses reveal that the number of papers including the keywords “environmental changed”or “climate change”have increased rapidly since 2004,(43)____When social scientists do tackle practical issues, their scope is often local: Belgium is interested mainly in the effects of poverty on Belgium for example .And whether the community’s work contributes much to an overall accumulation of knowledge is doubtful.The problem is not necessarily the amount of available funding (44)____this is an adequate amount so long as it is aimed in the right direction. Social scientists who complain about a lack of funding should not expect more in today`s economic climate.The trick is to direct these funds better. The European Union Framework funding programs have long had a category specifically targeted at social scientists. This year, it was proposed that system bechanged: Horizon 2020, a new program to be enacted in 2014, would not have such a category. This has resulted in protests from social scientists. But the intention is not to neglect social science; rather, the complete opposite. (45)____That should create more collaborative endeavors and help to develop projects aimed directly at solving global problems.[A] It could be that we are evolving two communities of social scientists: one that is discipline-oriented and publishing in highly specialized journals, and one that is problem-oriented and publishing elsewhere, such as policy briefs.[B] However, the numbers are still small: in 2010, about 1,600 of the100,000 social-sciences papers published globally included one of these keywords.[C] The idea is to force social to integrate their work with other categories, including health and demographic change food security, marine research and the bio-economy, clear, efficient energy; and inclusive, innovative and secure societies.[D] The solution is to change the mindset of the academic community, and what it considers to be its main goal. Global challenges and social innovation ought to receive much more attention from scientists, especially the young ones.[E] These issues all have root causes in human behavior. All require behavioral change and social innovations, as well as technological development. Stemming climate change, for example, is as much about changing consumption patterns and promoting tax acceptance as it is about developing clean energy.[F] Despite these factors, many social scientists seem reluctant to tackle such problems. And in Europe, some are up in arms over a proposal to drop a specific funding category for social-science research and to integrate it within cross-cutting topics of sustainable development.[G] During the late 1990s , national spending on social sciences and the humanities as apercentage of all research and development funds-including government, higher education, non-profit and corporate -varied from around 4% to 25%; in most European nations , it is about 15%.

(10 points) It is speculated that gardens arise from a basic need in the individuals who made them: the need for creative expression. There is no doubt that gardens evidence an impossible urge to create, express, fashion, and beautify and that self-expression is a basic human urge; (46) Yet when one looks at the photographs of the garden created by the homeless, it strikes one that, for all their diversity of styles, these gardens speak of various other fundamental urges, beyond that of decoration and creative expression.One of these urges had to do with creating a state of peace in the midst of turbulence, a “still point of the turning world,”to borrow a phrase from T. S. Eliot. (47)A sacred place of peace, however crude it may be, is a distinctly human need, as opposed to shelter, which is a distinctly animal need. This distinction is so much so that where the latter is lacking, as it is for these unlikely gardens, the former becomes all the more urgent. Composure is a state of mind made possible by the structuring of one’s relation to one’s environment. (48) The gardens of the homeless which are in effect homeless gardens introduce from into an urban environment where it either didn’t exist or was not discernible as such. In so doing they give composure to a segment of the inarticulate environment in which they take their stand.Another urge or need that these gardens appear to respond to, or to arise from is so intrinsic that we are barely ever conscious of its abiding claims on us. When we are deprived of green, of plants, of trees, (49) most of us give into a demoralization of spirit which we usually blame on some。

**The Essence of Freedom**Freedom is an innate desire within every human being, embodying the essence of personal autonomy and choice. It transcends physical boundaries, encompassing the liberty to think, act, and express oneself without constraint. This fundamental aspect of human nature is not merely a concept but a cornerstone of societal progress and individual fulfillment.At its core, freedom empowers individuals to pursue their aspirations and shape their destinies. It nurtures creativity and innovation, enabling the exploration of new ideas and the development of diverse perspectives. Whether in the arts, sciences, or personal endeavors, freedom fosters an environment where individuals can push boundaries, challenge norms, and contribute meaningfully to society.Moreover, freedom encompasses the right to self-determination and the pursuit of happiness. It entails the liberty to make choices that align with one's values and beliefs, fostering a sense of fulfillment and purpose in life. From career paths to personal relationships, freedom allows individuals to forge their own paths and embrace opportunities for growth and self-discovery. Beyond individual liberties, freedom plays a pivotal role in shaping collective progress and societal harmony. It underpins democratic principles, ensuring equal rights and opportunities for all members of society. By safeguarding freedom of speech, assembly, and expression, societies promote transparency, accountability, and civic engagement, thereby fortifying the foundations of democracy.However, the pursuit of freedom is not without challenges. Societal norms, political ideologies, and cultural traditions can impose constraints on individual liberties, stifling creativity and perpetuating inequalities.

### The Nature of FreedomFreedom is a fundamental aspect of human existence, often perceived as the ability to act, speak, and think without external restraints. However, the essence of freedom extends beyond mere liberties; it encompasses the intrinsic nature of individuals to strive for self-determination and personal growth. This essay explores the multifaceted dimensions of freedom, examining its philosophical underpinnings and societal implications.#### Philosophical FoundationsFreedom finds its roots in philosophical thought, particularly in the works of Jean-Jacques Rousseau and John Stuart Mill. Rousseau's idea of the "General Will" asserts that individuals should act in accordance with the common good, implying a societal framework within which personal freedoms are exercised. Mill, on the other hand, emphasizes the harm principle, which posits that individuals should be free to do as they wish unless their actions harm others.These philosophical viewpoints highlight the dual nature of freedom: the individual's right to autonomy versus the collective responsibility to society. Freedom thus becomes a balance, a continuous negotiation between personal desires and communal values.#### Societal ImplicationsIn the societal context, freedom manifests in various forms, such as political freedom, economic freedom, and social freedom. Political freedom ensures citizens' rights to participate in governance, to have a say in decisions that affect their lives. It is the cornerstone of democratic societies, where the rule of law and civil liberties are upheld.Economic freedom, often tied to the free market ideology, allows individuals to engage in trade and entrepreneurship without undue governmental interference. It fosters innovation and economic growth, yet it must coexist with regulations that ensure equitable distribution of wealth and opportunities.Social freedom concerns the rights and liberties individuals enjoy in their daily lives, including the freedom of expression, religion, and association. It is in these everyday freedoms that individuals find their identities and pursue their passions.#### Challenges to FreedomWhile the ideal of freedom is compelling, its realization is fraught with challenges. Authoritarian regimes, economic disparities, and cultural norms often present barriers to achieving true freedom. For instance, in societies where corruption is pervasive, political freedoms can be curtailed, and citizens may find it difficult to exercise their rights. Moreover, the tension between individual freedoms and collective well-being often leads to conflicts. Environmental regulations, public health mandates, and social justice initiatives frequently require restrictions on personal freedoms, raising ethical and practical dilemmas.#### ConclusionFreedom, at its core, is about the pursuit of autonomy and the capacity to shape one's destiny. Philosophically grounded and socially enacted, it represents a dynamic interplay betweenpersonal aspirations and communal responsibilities. As societies evolve, so too must our understanding of freedom, ensuring that it remains a beacon of hope and progress. In embracing the nature of freedom, individuals and communities alike can strive for a world where liberty is not merely a right, but a lived reality.。
英语四级作文对自由的看法Freedom is a fundamental human aspiration that has been a central theme throughout history. It is a multifaceted concept, encompassing various dimensions such as political freedom, personal autonomy, economic freedom, and freedom of expression. This essay delves into the significance offreedom in contemporary society, the challenges it faces, and its role in fostering human development and societal progress.Freedom, at its core, is the power to act, speak, orthink without external restraint. It is a cornerstone of democratic societies, where the rule of law, civil liberties, and political rights are upheld to ensure that individualscan pursue their own paths and make choices that reflecttheir personal values and beliefs. The value of political freedom cannot be overstated, as it allows citizens to participate in governance, express dissent, and hold leadersaccountable. This democratic participation is essential for maintaining the balance of power and preventing tyranny.Personal autonomy, another critical aspect of freedom, refers to an individual's ability to make decisions abouttheir own life. This includes choices related to one's career, relationships, lifestyle, and body. Personal autonomy is deeply connected to the concept of human dignity, as it acknowledges and respects the individual's right to self-determination. Without personal autonomy, individuals are deprived of the agency to shape their destinies, leading to a sense of powerlessness and subjugation.Economic freedom is equally important, as it provides individuals with the opportunity to improve their standard of living and achieve financial independence. This includes the freedom to work, to choose one's occupation, to engage in business, and to participate in the market economy. Economic freedom is a driver of innovation, entrepreneurship, andeconomic growth. It empowers people to take risks, invest in their ideas, and contribute to the overall prosperity of society. However, economic freedom must be balanced with social equity to ensure that all members of society have access to opportunities and resources.Freedom of expression is a fundamental human right that underpins many other freedoms. It allows individuals to communicate their ideas, opinions, and beliefs without fear of censorship or retaliation. Freedom of expression is essential for the exchange of ideas, the pursuit of truth, and the functioning of a democratic society. It enables the media to operate freely, which is crucial for informed citizenry and transparency in governance. However, this freedom also comes with the responsibility to avoid harm, such as hate speech or misinformation, which can undermine social cohesion and public trust.Despite its importance, freedom faces numerous challenges in today's world. Authoritarian regimes, political repression, and censorship continue to threaten freedom in many parts of the globe. Even in democratic societies, issues such as mass surveillance, restrictions on civil liberties, and economic inequality can erode the foundations of freedom. The rise of digital technology has introduced new complexities, with concerns about privacy, data security, and the impact ofsocial media on public discourse.Moreover, the COVID-19 pandemic has highlighted thetension between individual freedoms and collective safety. Measures such as lockdowns, travel restrictions, andmandatory vaccinations have sparked debates about the limitsof personal autonomy in the context of public health. These discussions underscore the need to balance individual rights with social responsibilities, recognizing that freedom is not absolute but must be exercised within the framework of mutual respect and the common good.In conclusion, freedom is a vital component of human existence and societal development. It empowers individualsto pursue their aspirations, fosters innovation and progress, and ensures the accountability of those in power. However, freedom must be safeguarded and balanced with other values such as equality, justice, and social responsibility. In an increasingly interconnected and complex world, the protection and promotion of freedom require constant vigilance, dialogue, and a commitment to upholding the principles of democracy and human rights. Through these efforts, we can strive to createa world where freedom is not only cherished but alsoaccessible to all.。
夸克英语作文Quarks: The Building Blocks of the UniverseIn the vast expanse of the universe, there exists a fundamental level of reality that has captivated the minds of scientists and philosophers alike. This realm, known as the subatomic world, is where the most fundamental particles of matter reside – the quarks.Quarks are the building blocks of hadrons, a class of particles that includes protons and neutrons, the constituents of atomic nuclei. These enigmatic particles were first proposed in 1964 by physicists Murray Gell-Mann and George Zweig, and their discovery has revolutionized our understanding of the fundamental structure of matter.At the heart of the quark model lies the concept of "color charge," a property that is unique to these particles. Unlike the familiar electric charge, which can be positive or negative, the color charge of quarks comes in three distinct varieties: red, green, and blue. This color charge is the driving force behind the strong nuclear force, one of the four fundamental forces of nature, which binds quarks together to form the more complex particles we observe in the world aroundus.The strong nuclear force is incredibly powerful, holding the quarks within a hadron together with such intensity that it would take an immense amount of energy to separate them. This property, known as "confinement," means that quarks can never be observed in isolation. They are always found in groups of twos (mesons) or threes (baryons), such as the protons and neutrons that make up the nuclei of atoms.One of the most fascinating aspects of quarks is their ability to exhibit a phenomenon known as "asymptotic freedom." As the distance between quarks decreases, the strong force becomes weaker, allowing the quarks to move more freely. Conversely, as the distance increases, the strong force becomes stronger, binding the quarks more tightly together. This behavior is the opposite of what we observe with the other fundamental forces, such as electromagnetism and gravity, which become weaker with increasing distance.The discovery of quarks has had a profound impact on our understanding of the fundamental structure of matter. It has led to the development of the Standard Model, a comprehensive theory that describes the interactions of the most fundamental particles in the universe. This model has been extensively tested and validatedthrough a vast array of experimental evidence, making it one of the most successful scientific theories in history.Beyond the realm of particle physics, the concept of quarks has also found applications in other fields of science. In astrophysics, for example, the study of quark matter, a hypothetical state of matter that may exist in the cores of the most dense and massive stars, known as neutron stars, has provided valuable insights into the behavior of matter under extreme conditions.Moreover, the study of quarks has also opened up new avenues of research in the field of quantum chromodynamics (QCD), a branch of quantum field theory that describes the strong interactions between quarks and gluons, the force carriers of the strong nuclear force. QCD has become a crucial tool in understanding the behavior of strongly interacting systems, from the dynamics of subatomic particles to the formation of the early universe.In conclusion, the discovery of quarks has been a transformative event in the history of science. These fundamental particles have not only deepened our understanding of the building blocks of the universe but have also inspired new areas of research and technological advancements. As we continue to explore the mysteries of the subatomic world, the study of quarks willundoubtedly continue to yield new insights and push the boundaries of our knowledge.。
a r X i v :0705.1883v 1 [h e p -p h ] 14 M a y 2007Asymptotic freedom in massive Yang-Mills theoryJ.Gegelia 11Institut f¨u r Kernphysik,Johannes Gutenberg-Universit¨a t,J.J.Becherweg 45,D-55099Mainz,GermanyandHigh Energy Physics Institute of TSU,Tbilisi,Georgia(Dated:February 1,2008)An effective field theory model of the massive Yang-Mills theory is considered.Assuming that the renormalized coupling constants of ’non-renormalizable’interactions are suppressed by a large scale parameter it is shown that in analogy to the non-abelian gauge invariant theory the dimensionless coupling constant vanishes logarithmically for large values of the renormalization scale parameter.PACS numbers:11.10.Gh,03.70.+k,11.10.Hi The standard model (SM)is an established consistent theory of strong,electromagnetic and weak interactions.It describes most of the known phenomena in elementary particle physics.The modern point of view is to think of the SM as an effective field theory,“low-energy approximation to a deeper theory that may not even be a field theory,but something different like a string theory”[1].While the effective Lagrangian consists of an infinite number of terms,the non-renormalizable interactions are suppressed by powers of a large scale.This makes the contributions of these interactions negligible for energies much lower than the large scale.Renormalizability in the traditional sense is not considered as a fundamental principle but rather a property of the leading order approximation to the full effective theory.The SM takes gauge invariance as a starting point.In modern string theories [2]one first notices a state of mass zero and unit spin among the normal modes of a string,and then from that deduces the gauge invariance of the effective field theory that describes such particles [1].In modern approach one usually takes gauge invariance as the starting point.Referring again to Weinberg’s book,“It is too soon to tell which of these two alternatives corresponds to the logical order of nature”[1].Taking into account the above considerations it is not evident that the gauge invariance principle should be applied to weak interaction as it is not mediated by massless vectors.As the fundamental nature of both the gauge invariance and the renormalizability seems to be questionable,the role of the scalar sector of the electro-weak theory could be also questioned,especially as the experimental status of the scalar Higgs particle remains still unclear.Therefore it seems interesting to have a closer look to effective field theory models of massive vector mesons which are not based on the concept of gauge invariance.In the present work an effective field theory model of the massive vector mesons interacting with fermions is considered.I do not deal here with the most general effective Lagrangian,but instead add the mass term of the vector mesons to the standard QCD Lagrangian [3].Next I add an infinite number of non-renormalizable interactions which are required to absorb the divergences generated by loop diagrams of the perturbation theory.I assume that all coupling constants of non-renormalizable interactions are suppressed by powers of a Large scale parameter Λ.Under this assumption I study the renormalization group behavior of the dimensionless coupling constant to one-loop order.The aim of this work is to investigate if the asymptotic freedom of the non-abelian gauge theories [4,5]persist when the explicit mass term is introduced in the Lagrangian (For earlier works on asymptotically free massive Yang-Mills models see Refs.[6,7]).Notations below closely follow the book by Yndur´a in [3].Let us consider an EFT model described by the following bare Lagrangian:L =L QCD +M 24 a G µνa G aµν,(2)is the standard QCD Lagrangian [3]and L 1contains an infinite number of terms of non-renormalizable interactions which are necessary for the cancelation of divergences of loop diagrams.Let us investigate the renormalization group behavior of renormalized coupling constant g R by analyzing the B ¯ψψGreen’s function using dimensional regularization (with parameter n )in combination with the MS scheme.To carry out the renormalization let us introduce the renormalized quantitiesq j =Z 1/2q q j R ,B µa =Z 1/2B B µa,R ,m q =Z −1m m q,R ,M 2=Z −1M M 2R ,g =Z −1g g R ,···,(3)(where···stands for parameters hidden in L1)and choose Z q,Z B,Z m,Z M,Z g,···such that all Green’s functions arefinite order-by-order in loop expansion.The sum of one-particle irreducible diagrams contributing in vector-meson propagator is parameterized as−iΠµνand to one loop order consists of a fermion and vector meson contributions.Divergent part of the contribution of all n f fermions reads:ΠµνF;ab =−2T Fδabg2R3Nǫn f,(4)where Nǫ=2/(4−n)and T F=1/2.This has to be canceled by counter-term contribution generated by Z B. Divergent part of the contribution of vectorfields is given asΠµνab;g =C Aδab g2R12M4 .(5)Thefirst term in square brackets in Eq.(5)is canceled by mass counter-term,second is canceled by Z B and the third term is taken care by counter-term contributions generated by higher-order terms hidden in L1.Field redefinition constant obtained from Eqs.(4)and(5)readsZ B=1+g2R2−4T F n f16π2µ4−n C Fδji Nǫ 3m−m32M2p/−p232π2M2C F Nǫ.(8) This gives the corresponding counter-term diagram contribution in B¯ψψvertex functioniΓ(1)µ,Z qija =3i g3R m2 64π2m232π2m22C A t a jiµ4−n Nǫγµ.(11)For the momentum-independent divergent part of the sum of two diagrams we obtainiΓ(1)µija +iΓ(2)µija=−3i g3R m232π2Nǫ 7C A3 .(13)For the corresponding running coupling constant α=g 2R /(4π)one obtainsα(µ)=α(µ0)2πln µ2−4T F n f。
