Lepton Flavour Violating B-s -> mu tau Decays in the General Two Higgs Doublet Model

Abstract

We study the lepton flavour-violating (LFV) B-s -> mu tau decays in the general two Higgs doublet model. Those LFV interactions could accommodate the present deviation of the muon anomalous magnetic moment and constrained by the recent measurements of the h -> mu tau decays at the LHC and the LFV tau decay processes such as tau -> mu mu mu and tau -> mu gamma. We find that the B-s -> mu tau decay rates could be sizable under the above experimental conditions in the framework of our model. These processes are expected to be observed at the colliders such as LHCb and Belle-II in the future.
