Description

The Lepton Flavour Universality (LFU) anomalies are currently one of the hottest topics in the particle physics community. A combination of recent results from LHCb, Belle and BaBar from semileptonic B decays have shown a discrepancy from the Standard Model prediction of ≈ 4 σ. I will review the latest lepton universality tests with semileptonic B mesons and present the prospects for an independent LFU test with baryons using semileptonic Λb→Λc decays. This test will help to corroborate the present anomalies and to provide complementary constraints on the possible origins of these anomalies beyond the Standard Model.
