Abstract

We investigate the rare radiative eta decay modes eta -> pi+ pi- gamma gamma and eta -> pi0 pi0 gamma gamma within the framework of chiral lagrangians at o(p^4) and present photon spectra for both processes.

Keywords

eta decay radiative decay chiral lagrangian photon spectrum rare decay
