Impact of Z′ boson on lepton flavor violating decays

Abstract

Recently, some small hints of lepton flavor violating (LFV) decays have been probed in different colliders and accelerators. Although these processes are forbidden in the Standard Model (SM), observation of LFV decays are considered as good probes to test theory beyond the SM. In this paper, we study some LFV decays, e.g. three-body decay channels of [Formula: see text] lepton like [Formula: see text], [Formula: see text] and two-body decays of B meson and [Formula: see text] lepton like [Formula: see text] and [Formula: see text] in [Formula: see text] model. We calculate the branching ratio of the above decays considering the effect of both [Formula: see text] and [Formula: see text]-mediated flavor-changing neutral-current (FCNC).
