The $\omega \sigma \gamma$-vertex in light cone QCD sum rules

Abstract

We investigate the $\omega \sigma \gamma$-vertex and estimate the coupling constant g${}_{\omega \sigma \gamma }$ in the framework of the light cone QCD sum rules. We compare our result with the values of this coupling constant deduced from a phenomenological analysis of $\omega \to \pi \pi \gamma$ decays.
