GUT-scale constrained SUSY in light of E989 muon g-2 measurement

TL;DR

This paper examines how recent muon g-2 measurements challenge GUT-scale constrained SUSY models, analyzing tensions with other experiments and exploring extensions to reconcile the data.

Contribution

It provides a comprehensive analysis of GUT-scale constrained SUSY models in light of new muon g-2 results, highlighting tensions and exploring extensions to address them.

Findings

Significant tension between muon g-2 and other experimental constraints in CMSSM/mSUGRA.

Extensions of SUSY models can alleviate the tension with muon g-2 data.

Analysis of muon g-2 implications in GMSB and AMSB SUSY breaking mechanisms.

Abstract

The new FNAL result of the muon $g-2$, combined with the BNL result, shows a 4.2$\sigma$ deviation from the SM. We use the new data of the muon $g-2$ to revisit several GUT-scale constrained SUSY models with the constraints from the LHC searches, the dark matter detection, the flavor data and the electroweak vacuum stability. We first demonstrate the tension between the muon $g-2$ and other experimental measurements in the CMSSM/mSUGRA. Then after discussing the possible ways to alleviate such a tension and showing the muon $g-2$ in pMSSM under relevant experimental constraints, we survey several extensions of the CMSSM/mSUGRA with different types of universal boundary conditions at the GUT scale. Finally, we briefly discuss the muon $g-2$ in other popular SUSY breaking mechanisms, namely the GMSB and AMSB mechanisms and their extensions.
