Description

There are four models of tree-level new physics (NP) that can potentially simultaneously explain the $b \to s \mu^+\mu^-$ and $b \to c \ell^- {\bar\nu}$ anomalies. They are the S3, U3, and U1 leptoquarks, and a triplet of standard-model-like vector bosons (VBs). In this talk, I describe an analysis of these models with general couplings. We find that, even in this most general case, $S_3$ and $U_3$ are excluded. For the U1 model, I discuss the importance of the constraints from lepton- flavor-violating processes. As for the VB model, it is shown to be excluded by the LHC bounds on high-mass resonant dimuon pairs. This conclusion is reached without any assumptions about the NP couplings.
