Chiral dynamics predictions for η' → η π π in several frameworks

Abstract:

We study the decay η' → η π π in three different chiral invariant approaches: Chiral Perturbation Theory, Resonance Chiral Theory both in Large -Nc, and also Linear Sigma Model. We analyze its Dalitz plot and the invariant mass spectra. We also compare the relevance of the isoscalar and isovector channels in these approaches.
