Wino-Higgsino dark matter in the MSSM from the $g-2$ anomaly

TL;DR

This paper demonstrates that wino-Higgsino dark matter in the MSSM, explaining the muon g-2 anomaly, can be tested by upcoming direct detection experiments and LHC searches, providing a promising avenue for discovery.

Contribution

It shows that the wino-Higgsino dark matter scenario consistent with the muon g-2 anomaly can be tested by near-future experiments and collider data.

Findings

Wino-Higgsino dark matter is detectable in upcoming direct detection experiments.

LHC experiments can potentially confirm or exclude the SUGRA explanation of the muon g-2 anomaly.

The parameter space explaining muon g-2 is accessible to near-future searches.

Abstract

In this letter, we show that the wino-Higgsino dark matter (DM) is detectable in near future DM direct detection experiments for almost all consistent parameter space in the spontaneously broken supergravity (SUGRA) if the muon g-2 anomaly is explained by the wino-Higgsino loop diagrams. We also point out that the present and future LHC experiments can exclude or confirm this SUGRA explanation of the observed muon g-2 anomaly.
