The new FNAL result of the muon , combined with the BNL result, shows a 4.2σ deviation from the SM. We use the new data of the muon to revisit several GUT-scale constrained SUSY models with the constraints from the LHC searches, the dark matter detection, the flavour data and the electroweak vacuum stability. We first demonstrate the tension between the muon and other experimental measurements in the CMSSM/mSUGRA. Then after discussing the possible ways to alleviate such a tension and showing the muon 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 in other popular SUSY breaking mechanisms, namely the GMSB and AMSB mechanisms and their extensions.

根据新的μ子 g-2 测量,GUT 尺度约束 SUSY
μ子的新FNAL结果 结合 BNL 结果,显示与 SM 的偏差为 4.2 σ。我们使用μ子的新数据在 LHC 搜索、暗物质检测、风味数据和弱电真空稳定性的约束下,重新审视几个 GUT 尺度约束 SUSY 模型。我们首先证明介子之间的张力和 CMSSM/mSUGRA 中的其他实验测量。然后在讨论了缓解这种紧张的可能方法并展示了μ子之后在相关实验约束下的 pMSSM 中,我们调查了 CMSSM/mSUGRA 的几种扩展,在 GUT 尺度上具有不同类型的通用边界条件。最后,我们简要讨论μ子 在其他流行的 SUSY 破解机制中,即 GMSB 和 AMSB 机制及其扩展。
