Pion transition form factor in the Domain model of QCD vacuum
Abstract
Domain model of QCD allows for description of wide range of meson observables, dynamical chiral symmetry breaking, and resolution of and strong problems. The purpose of the present study is transition form-factor of neutral pseudoscalar mesons, and how they are influenced by the typical vacuum configurations of the model -- almost everywhere homogeneous Abelian (anti-)self-dual fields. Asymptotic behavior of the calculated pion form-factor supports Belle trend, but the asymptotic value of differs from the prediction of factorization theorems.
