The Dark $Z'$ and Sterile Neutrinos Behind Current Anomalies

TL;DR

This paper explores how a light, 'dark' Z' boson and sterile neutrinos within a B-L extended Standard Model can explain current anomalies like the muon g-2 discrepancy and sterile neutrino signals.

Contribution

It introduces a model linking a light Z' and sterile neutrinos to observed anomalies, providing a unified theoretical framework.

Findings

Light Z' can account for muon g-2 anomaly

Sterile neutrinos explain neutrino experiment signals

Model aligns with current experimental data

Abstract

We show how, in the $B-L$ extension of the SM (BLSM) with an Inverse Seesaw (IS) mechanism for neutrino mass generation, a light $Z'$ state with moderate couplings to SM objects, hence `dark' in its nature, can be associated, in conjunction with light sterile neutrinos, to some present day data anomalies, such as the anomalous magnetic moment of the muon as well as a possible signal indicating the existence of sterile neutrinos in neutrino beam experiments.
