Abstract

We study the radiative phi -> K-0(K) over bar (0)gamma decay within a phenomenological framework by considering the contributions of the f(0)(980) and a(0)(980) scalar resonances. We calculate the branching ratio B(phi -> K-0(K) over bar (0)gamma) by employing the coupling constants g(f0)K(+)K(-) and g(a0)K(+)K(-) as determined by different experimental groups.
