Özet

We employ QCD sum rules and utilize omegaphi-mixing to calculate the coupling constants g(phisigmagamma) and g(phia0gamma) by studying the three point phisigmagamma- and phia(0)gamma-correlation functions. Our results are consistent with the previous estimations of these coupling constants in the literature.
