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 charged-current decays of B mesons have shown a discrepancy from the Standard Model prediction of ~3 σ. This talk will review the latest lepton universality tests with b → clν decays and present the progresses for an independent LFU test with baryons using baryonic Λb→Λc decays. This test is important both to corroborate the present anomalies and to provide complementary constraints on the possible origins of these anomalies beyond the Standard Model.
