Description
In the Standard Model electroweak interactions are strictly lepton flavour universal.
In view of the emerging hints for the violation of lepton flavour universality in several $B$-meson decays, we conduct a model-independent study (effective field theory approach) of several well-motivated new physics scenarios.
Taking into account the most recent LHCb data, we provide updates to New Physics fits for numerous popular hypotheses.
We also consider a promising model of vector leptoquarks,
which in addition to explaining the $B$-meson decay anomalies ($R_{K^{(*)}}$ and $R_{D^{(*)}}$) would have an extensive impact for numerous flavour observables.
