Violation of lepton universality would be a smoking gun for physics beyond the SM. Using semitauonic B decays, LHCb finds a value of R(D∗) = B(B0 → D∗+τ-vτ)/B(B0 → D∗+μ-νμ) = 0.336±0.027(stat) ±0.030(syst), which is 2.1 standard deviations larger than the value expected from the SM. Moreover, the measurement of the CP asymmetry in mixing of B0s mesons is highly sensitive to physics beyond the SM. This article presents the latest result on semileptonic asymmetries; using the full Run 1 dataset, it is found that assl = (0.39 ± 0.26(stat) ±0.20(syst))%, which is consistent with the Standard Model.
