Abstract

The coupling constants of a(0) --> omega gamma, f(0) --> omega gamma, a(0) --> rho gamma, and f(0) --> rho gamma are calculated using 3-point QCD sum rules. We estimate the coupling constants g(a0 omega gamma), g(f0 omega gamma), g(a0 rho gamma) and g(f0 rho gamma) which are an essential ingredient in the analysis of physical processes involving isoscalar f(0)(980) and isovector a(0)(980) mesons.
