Lepton flavor violating decays

Abstract

A number of measurements in decays induced by the semileptonic b → s and b → c transitions hint towards a possible role of new physics in both sectors. Motivated by these anomalies, we investigate the lepton flavor violating decays. We calculate the two-fold angular distribution of decay in the presence of vector, axial-vector, scalar and pseudo-scalar new physics interactions. We then compute the branching fraction and lepton forward–backward asymmetry in the framework of vector leptoquark which is a viable solution to the current B anomalies. We find that the upper limits are and at 90% C.L.
