Unified resolution of the $R(D)$ and $R(D^{\ast })$ anomalies and the lepton flavor violating decay $h\to \mu \tau$

Abstract

Taking advantage of the fact that the flavor of the neutrino in semileptonic $B$ decays $B\to D^{(\ast )}\tau \nu$ is not known, we show how a minimal set of higher-dimensional lepton flavor violating (LFV) operators can explain the $R(D^{(\ast )})$ anomalies, and as a spin-off, can give rise to the LFV decay of the Higgs boson, $h\to \mu \tau$. We also show how none but the minimal set of operators survive the present data.
