Agaev ∗High Energy Physics Lab., Baku State University, Z.Khalilov st.23, 1370148Baku, Azerbaijan Abstract The pion and kaon electromagnetic form factors F M (Q 2) are calculat
ed at the leading order of pQCD using the running coupling constant method. In calculations the leading and next-to-leading order terms in α2S ((1−x )(1−y ) Q 2) expansion in terms of αS (Q ) are taken into account. The resummed expression for F M (Q 2) is found. Results of numerical calculations for the pion (asymptoticdistribution amplitude) are presented.
