Lepton Universality measurements in semileptonic decays of b-quark hadrons in the LHCb experiment at CERN / Lomba Castro, Julian
Lepton Flavour Universality (LFU) is an assumed symmetry within the Standard Model (SM) that implies that the coupling between gauge bosons and the different leptons does not depend on the flavour (family) of the lepton [...]
