Final state hadronic interactions and non-resonant $B^\pm\to K^\pm\pi^+\pi^-$ decays

TL;DR

This paper investigates the non-resonant decay amplitude of B mesons into K pi pi final states, showing that final state hadronic interactions cause observable inhomogeneities in the decay distribution.

Contribution

It introduces a meson exchange-based approach to model final state interactions in B decays, providing new insights into non-resonant decay mechanisms.

Findings

Final state interactions create inhomogeneities in the Dalitz plot.

The meson exchange model effectively describes non-resonant decay amplitudes.

Inhomogeneities can be linked to specific hadronic interaction mechanisms.

Abstract

We evaluate the non-resonant decay amplitude of the process $B^\pm\to K^\pm\pi^+ \pi^-$ using an approach based on final state hadronic interactions described in terms of meson exchanges. We conclude that this mechanism generates inhomogeneities in the Dalitz plot of the B decay.
