Description

An instanton-induced pion wave function is constructed. It provides an intrinsic K-dependence which suppresses soft virtual one-gluon exchanges and thus legitimates the perturbative QCD (pQCD) calculations of the pion electromagnetic form factor in the region of momentum transfers above the scale Qc> (√3/(2√f)) (1/varρc) ∼ 1GeV
