Abstract

The coupling constants g(rhoetagamma) and g(omegaetagamma) are calculated using QCD sum rules method by studying the three point rhoetagamma and omegaetagamma correlation functions. A comparison of the results with the values of the coupling constants that are deduced from the experimentally measured decay, widths of rho --> etagamma and omega --> etagamma decays is performed.
