Abstract

We present a calculation of the coupling constant of f₀→ργ and a₀→ργ decays from the point of view of the light cone QCD sum rules. We estimate the coupling constants g_f0ργ, which are an essential ingredient in the analysis of physical processes involving the isoscalar f₀(980) and the isovector a₀(980) mesons.
