Abstract Decays into three particles are often described in terms of two-body resonances and a non-interacting spectator particle. To go beyond this simplest isobar model, crossed-channel rescattering effects need to be accounted for. We quantify the

Abstract We construct hadronic amplitudes for the three-body decays η (′) → π + π − π 0 and η′ → ηπ + π − in a non-perturbative fashion, allowing for C- and CP-violating asymmetries in the π + π − distributions. These amplitud

Abstract We study the quark-mass dependence of $$\omega \rightarrow 3\pi $$ ω→3π decays, based on a dispersion-theoretical framework. We rely on the quark-mass-dependent scattering phase shift for the pion–pion P-wave extracted from unitarized

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 ful

We construct hadronic amplitudes for the three-body decays $\eta^{(\prime)}\to\pi^+\pi^-\pi^0$ and $\eta'\to\eta\pi^+\pi^-$ in a non-perturbative fashion, allowing for $C$- and $CP$-violating asymmetries in the $\pi^+\pi^-$ distributions. These ampli

We present dispersive analyses of mesonic three-body decay amplitudes based on the fundamental principles of analyticity, unitarity, and crossing. In this framework the leading final-state interactions are fully taken into account, with the resulting
