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

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.
