Are 3-4-1 models able to explain the upcoming results of the muon anomalous magnetic moment?

Abstract

In light of the upcoming measurement of the muon anomalous magnetic moment [Formula: see text], we revisit the corrections to [Formula: see text] in the context of the [Formula: see text] gauge symmetry. We investigate three models based on this gauge symmetry and express our results in terms of the energy scale at which the [Formula: see text] symmetry is broken. To draw solid conclusions we put our findings into perspective with existing collider bounds. Lastly, we highlight the difference between our results and those rising from [Formula: see text] constructions.
