Dispersion relations for $$\eta '\rightarrow \eta \pi \pi $$ η ′ → η π π
Abstract We present a dispersive analysis of the decay amplitude for $$\eta '\rightarrow \eta \pi \pi $$ η ′ → η π π that is based on the fundamental principles of analyticity and unitarity. In this framework, final-state interactions are fully taken into account. Our dispersive representation...
