Coupling Constants g_{\phi \sigma \gamma}and g_{\phi a0\gamma}as Derived from QCD Sum Rules

A. Gokalp, O. Yilmaz

We employ QCD sum rules and utilize \omega \phi -mixing to calculate the coupling constants g_{\phi \sigma \gamma}and g_{\phi a0\gamma}by studying the three point \phi \sigma \gamma - and \phi a₀\gamma -correlation functions. Our results are consistent with the previous estimations of these coupling constants in the literature.
