Test of lepton flavour universality with semi-tauonic decays of $b$-hadrons at LHCb
Lepton Flavour Universality (LFU) is enforced in the Standard Model by construction. Any violation of LFU would be a clear sign of new physics. Existing hints of non universality are already present. The semitauonic decays in particular, are sensitive to contributions from non-Standard-Model particl...
