Scientific paper

The pion and kaon electromagnetic form factors $F_M(Q^2)$ are calculated at
the leading order of pQCD using the running coupling constant method. In
calculations a dependence of the mesons distribution amplitudes on the hard
scale $Q^2$ is taken into account. The Borel transform and resummed expression
for $F_M(Q^2)$ are found.
