Final state hadronic interactions and non-resonant $B^{\pm }\to K^{\pm }\ddot{I}{€}^{+}\ddot{I}{€}^{-}$ decays

Abstract

We evaluate the non-resonant decay amplitude of the process $B^{\pm }\to K^{\pm }\ddot{I}{€}^{+}\ddot{I}{€}^{-}$ 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.
