Abstract

We present a calculation of the coupling constant of f(0) -> rho gamma and a(0) -> rho gamma decays from the point of view of the light cone QCD sum rules. We estimate the coupling constants g(f0 rho gamma) which are an essential ingredient in the analysis of physical processes involving the isoscalar f(0)(980) and the isovector a(0)(980) mesons.
