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

TL;DR

This paper derives one-loop expressions for lepton-flavor violating decays in a minimal left-right symmetric model, showing some decay rates could be detectable soon, linking neutrino data and muon g-2 anomalies.

Contribution

It provides new analytical formulas for LFV decays in a specific left-right model and explores their potential observability.

Findings

Some decay rates are near future experimental sensitivities.

The model accommodates neutrino oscillation data.

Connections between LFV decays and muon g-2 are discussed.

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 $Z\to e^\pm_b e_a^\mp$ 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 $SU(2)_R$ Higgs doublet accommodating data of neutrino oscillations and $(g-2)_{\mu}$. The numerical investigation indicates that some of these decay rates can reach near future experimental sensitivities.
