Muon Anomalous Magnetic Moment and mu -> e gamma in B-L Model with Inverse Seesaw

TL;DR

This paper investigates the muon anomalous magnetic moment and mu -> e gamma decay within a TeV-scale B-L extension of the Standard Model incorporating inverse seesaw, highlighting constraints and experimental prospects.

Contribution

It provides a detailed analysis of B-L model contributions to muon g-2 and lepton flavor violation, emphasizing parameter space compatibility with current experiments.

Findings

B-L contributions to a_mu are highly constrained, preserving the SM value.

The model can satisfy current mu -> e gamma decay limits across a broad parameter space.

Predictions suggest potential observability in upcoming MEG experiments.

Abstract

We study the anomalous magnetic moment of the muon, a_\mu, and lepton flavor violating decay \mu -> e \gamma in TeV scale B-L extension of the Standard Model (SM) with inverse seesaw mechanism. We show that the B-L contributions to a_\mu are severely constrained, therefore the SM contribution remains intact. We also emphasize that the current experimental limit of BR(\mu -> e \gamma) can be satisfied for a wide range of parameter space and it can be within the reach of MEG experiment.
