Abstract

The study of the B⁺ → K⁺ decay channel at LHCb offers great opportunities to study different aspects of the Standard Model and possibly Beyond Standard Model physics. In particular it can be interesting not only for the possibility to measure CP asymmetry but also to study possible intermediate resonances. The ratios of the branching fractions of the B⁺ → K⁺ decay channel, of the charmless component with < 2.85 GeV/c² and of the charmonium contribution η_c relative to the J/ψ are presented.
