We study the radiative phi -> K+K-gamma decay within a phenomenological framework by considering the contributions of the f(0)(980) and a(0)(980) scalar resonances. We consider the kaon-loop model and the no-structure model to evaluate these contributions and compare the results obtained in two models. (C) 2008 Elsevier B.V. All rights reserved.
