Description
I will discuss the possibility to explain recent anomalies in semileptonic B decays at LHCb via a composite Higgs model, in which both the Higgs and a triplet leptoquark arise as pseudo-Goldstone bosons of the strong dynamics. Fermion masses are assumed to be generated via the mechanism of partial compositeness, which largely determines the leptoquark couplings and implies non-universal lepton interactions. The latter are needed to accommodate tensions in the b→sμμ dataset and to be consistent with a discrepancy measured at LHCb in the ratio of B+→K+μ+μ− to B+→K+e+e− branching ratios.
