A brief survey of low energy supersymmetry under current experiments

TL;DR

This survey reviews the status of low energy supersymmetry, especially the MSSM, in light of current experimental constraints from LHC, dark matter detection, muon g-2, and W-boson mass measurements, highlighting its viability and challenges.

Contribution

It provides a comprehensive overview of how the MSSM stands against recent experimental results, emphasizing its survival, parameter space constraints, and potential signals at future colliders.

Findings

MSSM can survive current experimental constraints.

Dark matter relic density is achievable via neutralino freeze-out.

Muon g-2 anomaly can be explained within MSSM at 2-sigma.

Abstract

This is a brief overview on the low energy supersymmetry in light of current experiments including the LHC searches, the dark matter (DM) detections, the muon g-2 and the CDF II measurement of the W-boson mass. We focus on the minimal framework of supersymmetry, namely the minimal supersymmetric model (MSSM), and obtain the following conclusions: (i) The MSSM can survive all current experiments, albeit suffering from the little hierarchy problem due to the heavy stops pushed up by the LHC searches; (ii) The DM relic density can be readily achieved by the thermal freeze-out of the lightest neutralino and the null results of DM direct detections are typically driving the parameter space to the bino-like lightest neutralino region; (iii) The muon g-2 anomaly reported by FNAL and BNL can be explained at 2-sigma level, which indicates light sleptons and electroweakinos possibly accessible at the HL-LHC; (iv) The CDF II measurement of the W-boson mass can be marginally explained, but requires light stops near TeV which may soon be covered by the LHC searches.
