Connection of $g-2_{\mu}$, electroweak, dark matter, and collider constraints on 331 models

TL;DR

This paper analyzes various 3-3-1 models to explain the muon g-2 anomaly by calculating their contributions and combining electroweak, dark matter, and collider constraints to identify viable parameter spaces.

Contribution

It provides a comprehensive calculation of muon g-2 contributions across multiple 3-3-1 models and explores their compatibility with current experimental constraints.

Findings

Identifies parameter regions in 3-3-1 models that can explain the muon g-2 anomaly.

Derives bounds on model parameters based on current and future experimental data.

Highlights the complementarity of different experimental constraints in testing 3-3-1 models.

Abstract

In this work we compute all contributions to the muon magnetic moment stemming from several 3-3-1 models namely, minimal 331, 331 with right handed neutrinos, 331 with heavy neutral leptons, 331 with charged exotic leptons, 331 economical and 331 with two higgs triplets. Further, we exploit the complementarity among current electroweak, dark matter and collider constraints to outline the relevant parameter space of the models capable of explaining the anomaly. Lastly, assuming that the experimental anomaly has been otherwise resolved, we derive robust $1\sigma$ bounds using the current and projected measurements.
