Description
Recent studies of rare semileptonic decays of beauty mesons reported some intriguing discrepancies with the SM predictions, which seem to form a coherent pattern. Of particular interest are the angular observable P5' of the B→Kμ+μ- decay and the suppression of the muon channel in the ratios of branching fractions of B+→K+μ+μ− to B+→K+e+e− transitions.
The proposed research aims to perform an unbinned likelihood amplitude fit of B→ Kl+l- decays with the full LHCb run-I/II dataset, simultaneously to the muon and electron channel. This approach intends to disentangle the hadronic-dependent part from a q2-independent New Physics(NP) contribution in a theoretically accurate and experimentally sensitive manner, establishing eventually an evidence of NP.
