Abstract

The Standard Model predictions about the universality of the gauge boson couplings to charged leptons have been tested in B meson semileptonic decays. Several measurements of charged-current and neutral current processes were performed with a data sample collected with the LHCb detector in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb −1 . This review presents recent results that manifest some anomalies challenging the SM paradigm. Prospects for future measurements to elucidate the origin of these anomalies are also discussed.
