Abstract

The new FNAL result of the muon g2g-2, combined with the BNL result, shows a 4.2σ\sigma deviation from the SM. We use the new data of the muon g2g-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 g2g-2 and other experimental measurements in the CMSSM/mSUGRA. Then after discussing the possible ways to alleviate such a tension and showing the muon g2g-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 g2g-2 in other popular SUSY breaking mechanisms, namely the GMSB and AMSB mechanisms and their extensions.
