$(g - 2)_{e, μ}$ and Lepton flavor violating decays in a left-right model

arXiv:2409.01390

Abstract

General expressions for one-loop contributions associated with lepton-flavor violating decays of the standard model-like Higgs boson $h \to e_{b}^{\pm} e_{a}^{\mp}$ and gauge boson $Z \to e_{b}^{\pm} e_{a}^{\mp}$ are introduced in the unitary gauge. The results are used to discuss these decays as new physics signals in a minimal left-right symmetric model containing only one bidoublet Higgs and a $S U (2)_{R}$ Higgs doublet accommodating data of neutrino oscillations and $(g - 2)_{μ}$ . The numerical investigation indicates that some of these decay rates can reach near future experimental sensitivities.
