论文摘要
新的CDF II测量值$ W $ -BOSON质量显示了与标准模型（SM）预测的7 $σ$偏差，而Muon $ G-2 $的最新FNAL测量显示了SM的4.2 $σ$偏差（与BNL结果结合）。他们俩都强烈指出SM之外的新物理学。在这项工作中，我们研究了两种测量对低能超对称性的影响。通过对最小超对称标准模型（MSSM）的参数空间的广泛探索，我们发现，在当前的colleders和暗物质检测的当前实验限制允许的参数空间中，MSSM可以同时解释两种测量值，这两个测量值都在$2σ$水平的边缘上，将理论的不正确置于考虑。偏爱的参数空间的特征是Bino，Wino和Stau之间的压缩频谱，停止约为1 TEV，可能会在不久的将来的LHC搜索中覆盖。
The new CDF II measurement of $W$-boson mass shows a 7$σ$ deviation from the Standard Model (SM) prediction, while the recent FNAL measurement of the muon $g-2$ shows a 4.2$σ$ deviation (combined with the BNL result) from the SM. Both of them strongly indicate new physics beyond the SM. In this work we study the implication of both measurements on low energy supersymmetry. With an extensive exploration of the parameter space of the minimal supersymmetric standard model (MSSM), we find that in the parameter space allowed by current experimental constraints from colliders and dark matter detections, the MSSM can simultaneously explain both measurements on the edge of $2σ$ level, taking theoretical uncertainties into consideration. The favored parameter space, characterized by a compressed spectrum between bino, wino and stau, with the stop being around 1 TeV, may be covered in the near future LHC searches.
