Chiral loop and LsigmaM predictions for phi->pi0etagamma

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

A prediction for the contributions of chiral loops and the Lσ\sigmaM model to the radiative ϕπ0ηγ\phi\to\pi^0\eta\gamma decay mode is presented. The Lσ\sigmaM is used as an appropriate framework for describing the pole effects of the a0(980)a_0(980) scalar resonance. As a result, a better agreement with present available data is achieved for the higher part of the π0η\pi^0\eta invariant mass spectrum. For the branching ratio, a value of B(ϕπ0ηγ)=(0.75B(\phi\to\pi^0\eta\gamma)=(0.75--0.95)×1040.95)\times 10^{-4} is found.
