Explaining b → sl+l- and the Cabibbo angle anomaly with a vector triplet

The most statistically significant hints for new physics in the flavor sector are discrepancies between theory and experiment in B decays to lepton pairs (b -> sl(+)l(-)) and a deficit in the unitarity constraints to the 1st row of the Cabibbo-Kobayashi-Maskawa matrix (the Cabibbo angle anomaly). We propose that these anomalies can be reconciled by a simplified model with massive gauge bosons transforming in the adjoint representation of SU(2)(L). After calculating the impact of this model on B decays, observables testing charged current lepton flavor universality (LFU), electro-weak precision observables and LHC searches we perform a global fit to all available data. We find that our model can provide a consistent common explanation of both anomalies and that the fit to the data is more than 7 sigma better than the fit of the Standard Model. The model also predicts interesting correlations between LFU violation in the charged current and b -> sl(+)l(-) data which can be tested experimentally in the near future.
