Electromagnetic Form Factors of the Transition $\pi +{\gamma }^{\ast }\to A_1$

Abstract

Corrections due to gluon condensate to electromagnetic form factors of the transition $\pi +{\gamma }^{\ast }\to A_1$ are calculated by standard QCD sum rules technique. The obtained results are compared to the corresponding light-cone QCD sum rules.
