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.

    In the TNMSSM, the new CPV couplings χ_d and χ_t give significant contributions to EDMs, with neutron EDM data constraining their phases and b, c quark EDMs reaching 10^-22 and 10^-23 e·cm.

  2. Revisiting CMSSM with Non-Universal Gaugino Masses under Current Constraints

    hep-ph 2024-12 conditional novelty 4.0 of 10

    Current data restrict the g~-SUGRA scenario to tanβ ≳ 5 and M0 ≳ 20 tanβ GeV, with large muon g-2 contributions difficult and future colliders needed to cover the remaining parameter space.
