Linear flavour violation and anomalies in B physics

We propose renormalizable models of new physics that can explain various anomalies observed in decays of b-mesons to electron and muon pairs. the new physics states couple to linear combinations of standard model fermions, yielding a pattern of flavour violation that gives a consistent fit to the gamut of flavour data. accidental symmetries prevent contributions to baryon- and lepton-number-violating processes, as well as enforcing a loop suppression of new physics contributions to flavour violating processes. data require that the new flavour-breaking couplings are largely aligned with the yukawa couplings of the sm and so we also explore patterns of flavour symmetry breaking giving rise to this structure.
