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

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/204401We evaluate the non-resonant decay amplitude of the process $B^\pm\to K^\pmπ^+ π^-$ 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.6 pages, 5 figures. Major changes. Version accepted for publication in Phys. Lett.
