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

Abstract

We investigate the possibility of explanation for the muon anomalous magnetic moment $g_{\hat{I}}¼-2$ 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 $g_{\hat{I}}¼-2$. Stringent constraints due to lepton flavor violation $\hat{I}¼\to e{\hat{I}}^3$, $\hat{I}¼$-$e$~conversion and the electron anomalous magnetic moment $g_e-2$ are considered, and the results are compatible.
