Abstract

We propose a parametrization for intepreting some of the presently available data of the $B^{\pm} \to K^{\pm} p {\bar p}$ decay, in particular those by LHCb and Belle collaborations. The model is inspired by the well-known current and transition contributions, usually assumed in this kind of decay. However, in the light of considerations about the dominant graphs and about final state interactions, we modify some parameters of the model, determining them by means of a best fit to data. We show the results, which we discuss in some detail. Moreover we give some predictions on other observables relative to the decays.
