Abstract

recalculated the coupling constants of rho(omega) -> eta gamma and eta' -> rho(omega)gamma decays especially with loop contributions in the case of axial- vector coupling in the method of QCD sum rules for dimension d = 6. A comparison of our prediction on the coupling constants with the result obtained from analysis of the experimental data and calculations done before is performed.
