Muon $g-2$ anomaly in a left-right model with an inverse seesaw mechanism

TL;DR

This paper explores how a left-right model with an inverse seesaw mechanism can explain the muon g-2 anomaly, showing that certain parameter spaces accommodate the observed deviation while satisfying experimental constraints.

Contribution

It demonstrates that the muon g-2 anomaly can be explained within a left-right inverse seesaw model, considering significant loop contributions and experimental constraints.

Findings

Parameter space can accommodate muon g-2 deviation

Loop contributions from neutrinos and charged Higgs are significant

Results are consistent with lepton flavor violation constraints

Abstract

We investigate the possibility of explanation for the muon anomalous magnetic moment $g_\mu-2$ in a left-right model with an inverse seesaw mechanism. We emphasize that the observed deviation from the Standard Model predictions can be accommodated in a large part of the parameter space of this class of models, where loops with massive neutrinos and charged Higgs boson as well as the weak $W$ boson contribute significantly to $g_\mu-2$. Stringent constraints due to lepton flavor violation $\mu\to{e}\gamma$, $\mu$-${e}$~conversion and the electron anomalous magnetic moment $g_e-2$ are considered, and the results are compatible.
