Higgs boson decays with lepton flavor violation in the $B-L$ symmetric SSM

Abstract

Recently, the ATLAS and CMS Collaborations reported the latest experimental upper limits on the branching ratios of the lepton flavor violating (LFV) 125 GeV Higgs boson decays, $h\to e\mu$, $h\to e\tau$, and $h\to \mu \tau$. In this paper, we mainly investigate the LFV Higgs boson decays $h\to e\mu$, $h\to e\tau$, and $h\to \mu \tau$ in the minimal supersymmetric extension of the Standard Model with local $\text{B-L}$ gauge symmetry. At the same time, the corresponding constraints from the LFV rare decays $\mu \to e\gamma$, $\tau \to e\gamma$, $\tau \to \mu \gamma$, and muon $(g-2)$ are considered to analyze the numerical results.
