dc.description.abstract We study the rare decay B?K?2(1430)(?K?)?+?? in the Standard Model and beyond. Working in the transversity basis, we exploit the relations between the heavy-to-light form factors in the limit of heavy quark (mb??) and large energy (EK?2??) of the K?2 meson. This allows us to construct observables where, at leading order in ?QCD/mb and ?s, the form-factor dependence involving the B?K?2 transitions cancels. Higher-order corrections are systematically incorporated in the numerical analysis. In the Standard Model, the decay has a sizable branching ratio, and therefore a large number of events can be expected at LHCb. Going beyond the Standard Model, we explore the implications of the global fit to presently available b?s?+?? data on the B?K?2?+?? observables.
