Analysis of rescattering effects in $3 π$ final states

Dominik Stamen, Tobias Isken, Bastian Kubis +2

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 r…

Patterns of $C$ - and $C P$ -violation in hadronic $η$ and $η^{'}$ three-body decays

Hakan Akdag, Tobias Isken, Bastian Kubis

We construct hadronic amplitudes for the three-body decays $η^{(')} \to π^{+} π^{-} π^{0}$ and $η^{'} \to η π^{+} π^{-}$ in a non-perturbative fashion, allowing for $C$ - and $C P$ -violating asymmet…

Quark-mass dependence in $ω \to 3 π$ decays

Maximilian Dax, Tobias Isken, Bastian Kubis

We study the quark-mass dependence of $ω \to 3 π$ decays, based on a dispersion-theoretical framework. We rely on the quark-mass-dependent scattering phase shift for the pion-pion $P$ …

Dispersion relations for $η^{'} \to η π π$

Tobias Isken, Bastian Kubis, Sebastian P. Schneider +1

We present a dispersive analysis of the decay amplitude for $η^{'} \to η π π$ that is based on the fundamental principles of analyticity and unitarity. In this framework, final-state inte…
