Özet

We employ QCD sum rules to calculate the coupling constants g(rhopigamma) and g(rhopigamma) by studying the three point rhopigamma and omegapigamma correlation functions. Our results are in good agreement with the coupling constants g(rhopigamma) and g(omegapigamma) that are deduced utilizing the experimentally measured values of the Gamma(rho(0) --> pi(0)gamma) and Gamma(omega --> pi(0)gamma) decay widths.
