Final state hadronic interactions and non-resonant B±→K±π+π−B±→K±π+π− decays

We evaluate the non-resonant decay amplitude of the process B±→K±π+π−B±→K±π+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.
