Abstract
In the Standard Model, the coupling of the electroweak gauge bosons to each of the three charged leptons is identical. Recent measurements have shown hints that this principle may be violated, and may be due to new physics phenomena. The lepton universality tests performed with semileptonic $b$ decays with $\tau$ leptons by LHCb are presented and future prospects are discussed.
