Title: g{sub a{sub 0}}{sub {rho}}{sub {gamma}} and g{sub f{sub 0}}{sub {rho}}{sub {gamma}} coupling constants in three point QCD sum rules

Abstract

The coupling constant of a{sub 0}{yields}{rho}{gamma} and f{sub 0}{yields}{rho}{gamma} decays are calculated using 3-point QCD sum rules. We estimate the coupling constant g{sub a{sub 0}}{sub {rho}}{sub {gamma}} and g{sub f{sub 0}}{sub {rho}}{sub {gamma}} which are an essential ingredient in the analysis of physical processes involving isoscalar f{sub 0}(980) and isovector a{sub 0}(980) mesons.
