Probing the MSSM explanation of the muon g-2 anomaly in dark matter experiments and at a 100 TeV $pp$ collider

TL;DR

This paper investigates how current and future dark matter and collider experiments can test the MSSM explanation for the muon g-2 anomaly, highlighting the potential of upcoming experiments and colliders to probe relevant parameter space.

Contribution

It provides a comprehensive analysis of the MSSM parameter space consistent with muon g-2, dark matter relic density, and collider constraints, emphasizing the reach of future experiments and colliders.

Findings

Current XENON-1T data constrains MSSM parameter space for muon g-2.

A 100 TeV collider can explore most surviving MSSM samples via trilepton searches.

Compressed spectra may be probed by monojet searches at a 100 TeV collider.

Abstract

We explore the ability of current and future dark matter and collider experiments in probing anomalous magnetic moment of the muon, $(g-2)_\mu$, within the Minimal Supersymmetric Standard Model (MSSM). We find that the latest PandaX-II/LUX-2016 data gives a strong constraint on parameter space that accommodates the $(g-2)_{\mu}$ within $2\sigma$ range, which will be further excluded by the upcoming XENON-1T (2017) experiment. We also find that a 100 TeV $pp$ collider can cover most of our surviving samples that satisfy DM relic density within $3\sigma$ range through $Z$ or $h$ resonant effect by searching for trilepton events from $\tilde{\chi}^0_2\tilde{\chi}^+_1$ associated production. While the samples that are beyond future sensitivity of trilepton search at a 100 TeV $pp$ collider and the DM direct detections are either higgsino/wino-like LSPs or bino-like LSPs co-annihilating with sleptons. Such compressed regions may be covered by the monojet(-like) searches at a 100 TeV $pp$ collider.
