Abstract

We estimate the coupling constant g(phi sigma gamma)by using the three- point correlation function and we also investigate this coupling constant by studying the effective lagrangians. Here we consider the effect the phi-omega mixing effect to the calculation. Besides, a comparison of our predictions with the theoretical results existing in literature is presented.
