Abstract: We interpret the recent hints for lepton flavor universality violation in rare $B$ meson decays. Based on a model-independent effective Hamiltonian approach, we determine regions of new physics parameter space that give a good description… read more here.

Abstract: A measurement of the ratio of branching fractions of the decays B^{+}→K^{+}μ^{+}μ^{-} and B^{+}→K^{+}e^{+}e^{-} is presented. The proton-proton collision data used correspond to an integrated luminosity of 5.0 fb^{-1} recorded with the LHCb experiment at center-of-mass… read more here.

DOI: 10.1142/s0217751x22500051
Abstract: Lepton Flavor Universality Violation (LFUV) in B decays in both neutral b → sl+l− and charged b → clν̄l processes observed in the ratios RK(∗) and RD(∗) is investigated in the framework of a model… read more here.
