Investigation of g_f0-rho-gamma and g_a0-rho-gamma coupling constants in light cone sum rules

Abstract

We present a calculation of the coupling constant f0-->rho-gamma of and a0-->rho-gamma decays from the point of the light cone QCD sum rules. We estimate the coupling constants g_f0-rho-gamma and g_a0-rho-gamma which are an essential ingredient in the analysis of physical processes involving isoscalar f0(980) and isovector a0(980) mesons.
