1943por Buonaura, A“…This prediction is called lepton flavour universality (LFU) and is well tested in tree-level decays; any violation of LFU would be a clear sign of physics beyond the Standard Model. …”

1944por Au Yang, Ho Yin“…The Standard Model predicts that charged leptons such as electrons and muons should have identical electroweak interaction strengths, which is known as lepton flavour universality. However, in some specific beauty quark decays, recent experimental results indicate that the ratio between branching fractions of electron and muon channels of the same decay may be deviant from unity, suggesting violations of the universality. …”

1960por Rosner, Jonathan L.“…It is proposed that this universal quark separation is a fundamental dimensional constant of the strong interactions in the same sense as the pion decay constant, the QCD scale, or the light-quark constituent mass.…”
