# Probing minimal SUSY scenarios in the light of muon $g-2$ and dark matter

## TL;DR

This paper investigates minimal supersymmetric models that simultaneously address the muon g-2 anomaly and dark matter relic abundance, highlighting their testability at future collider and dark matter detection experiments.

## Contribution

It identifies specific SUSY scenarios with light bino, higgsino, and slepton that can explain both phenomena and assesses their experimental prospects.

## Key findings

- LHC can probe almost all parameter space via tau + missing energy searches.
- XENON1T and ILC can test large parts of the parameter space.
- Models with light bino, higgsino, and sleptons naturally explain muon g-2 and dark matter.

## Abstract

We study supersymmetric (SUSY) models in which the muon $g-2$ discrepancy and the dark matter relic abundance are simultaneously explained. The muon $g-2$ discrepancy, or a 3$\sigma$ deviation between the experimental and theoretical results of the muon anomalous magnetic moment, can be resolved by SUSY models, which implies at least three SUSY multiplets have masses of $\mathop{\mathcal{O}}(100)\, \mathrm{GeV}$. In particular, models with the bino, higgsino and slepton having $\mathop{\mathcal{O}}(100)\, \mathrm{GeV}$ masses are not only capable to explain the muon $g-2$ discrepancy but naturally contains the neutralino dark matter with the observed relic abundance. We study constraints and future prospects of such models; in particular, we find that the LHC search for events with two hadronic taus and missing transverse momentum can probe this scenario through chargino/neutralino production. It is shown that almost all the parameter space of the scenario can be probed at the high-luminosity LHC, and a large part can also be tested at the XENON1T experiment as well as at the ILC.
