Comparative analysis of the QCD sum-rule method and perturbative QCD for the process γ(γ) → π0
Description
By means of the QCD sum-rule method we investigate the dependence of the form factor of the process γ(1γ(2 → π0 on the momentum transfer Q2 = -q21 = -q22 in the whole region 0<Q2<infinity. We make a comparison with the first terms of the expansion of F0(Q2) in 1/Q2 in the asymptotic regime Q2 → infinity calculated in the framework of perturbative QCD
