Abstract

We study phia(0)gamma- and phisigmagamma-vertices in the framework of the light cone QCD sum rules and we estimate the coupling constants gphia(0)gamma and gphisigmagamma utilizing omega-phi mixing. We compare our results with the previous estimations of these coupling constants in the literature obtained from phenomenological considerations. (C) 2002 Elsevier Science B.V. All rights reserved.
