$$\eta ^{\prime }\rightarrow \eta \pi \pi $$ η′→ηππ decays in unitarized resonance chiral theory
Abstract We study the hadronic $$\eta ^{\prime }\rightarrow \eta \pi \pi $$ η′→ηππ decays within the framework of $$U(3)_{L}\otimes U(3)_{R}$$ U(3)L⊗U(3)R Chiral Perturbation Theory including resonance states and the complete one-loop corrections. The amplitude is projected in partial waves and unit...
