Lepton universality, flavour and number violation in $B$ and $\tau$ decays at LHCb
The LHCb experiment has explored lepton universality violation in b → c ` − ν ` and b → s ` + ` − transitions through the measurement of the ratios R ( D ∗ ) and R K . These ratios are found to be compatible with the Standard Model expectation at the level of 2.1 σ and 2.6 σ , respectively. Addition...
