Muon $g-2$ and Dark Matter in the MSSM

TL;DR

This paper explores how the MSSM can simultaneously explain dark matter and the muon g-2 anomaly, highlighting the potential of future experiments and colliders to test these scenarios.

Contribution

It identifies bino-like dark matter with co-annihilation as a promising MSSM scenario compatible with current bounds and discusses future experimental prospects.

Findings

Bino-like dark matter with co-annihilation explains both phenomena.

Next-generation experiments will probe much of the parameter space.

A future collider is necessary for full exploration.

Abstract

We investigate the possibility that both dark matter and the long-standing discrepancy in the anomalous magnetic moment of the muon may be explained within the MSSM. In light of the stringent bounds from direct detection, we argue that the most promising viable scenarios have bino-like dark matter produced via either bino-wino or bino-slepton co-annihilation. We find that the combination of next-generation direct detection experiments and the LHC will be able to probe much of the interesting parameter space, however a future high-energy collider is needed to comprehensively explore this scenario.
