Abstract

Power-suppressed corrections to the light pseudoscalar (pi, K) and longitudinally polarized rho -meson electromagnetic form factors F-M(Q(2)) are estimated by means of the running coupling constant method. In calculating themesons distribution amplitudes (DAs) found, the "naive non-abelianization"approximation is used. Comparisons are made with F-M(Q(2)) obtained using the "ordinary" DAs and running coupling constant method, as well as with frozen coupling approximation's results.
