Özet

We employ QCD sum rules to calculate the coupling constant g(rho sigma gamma) by studying the three-point rho sigma gamma correlation function. Our result is consistent with the value of this coupling constant obtained using vector meson dominance of the electromagnetic current and the experimental rho (o) photoproduction data.
