520 _ _ |a mass energy corresponding to the Ξ₯(4𝑆) resonance. These data, characterised by low particlemultiplicity, well-constrained initial-state kinematics, and excellent lepton identification, providean ideal environment to study lepton-flavour universality in semileptonic 𝐡 decays. We presentresults on the ratios of semitauonic decay rates compared to those to light leptons in both exclusiveand inclusive 𝐡 decay. These include new measurements of the ratios for exclusive 𝐡 β†’ 𝐷(βˆ—) β„“πœˆβ„“decays 𝑅(𝐷(βˆ—))𝜏/β„“ in events tagged by a semileptonic 𝐡 decay.
