A preliminary analysis of eta' -> eta pi pi in chiral theories

Abstract

Preliminary results for the Dalitz plot distribution of $η^\prime\toηππ$ decays in the frameworks of Large-$N_c$ Chiral Perturbation Theory and Resonance Chiral Theory are given. We hope our results to be of some relevance for the present and forthcoming analysis of these decays at GAMS, CLEO, VES, KLOE-2, Crystal Ball, Crystal Barrel, WASA, and BES-III.
