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

Authors

Description

We 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.
