论文摘要

鉴于当前的实验,包括LHC搜索,暗物质(DM)检测,MUON G-2和CDF II测量W-Boson质量,这是对低能超对称性的简要概述。我们专注于超对称性的最小框架,即最小的超对称模型(MSSM),并获得以下结论:(i)MSSM可以在所有当前的实验中生存,尽管由于LHC搜索而遭受了较大的层次结构问题; (ii)DM液体密度可以通过最轻的中性诺的热冷冻输出很容易实现,而DM直接检测的无效结果通常是将参数空间驱动到Bino-like最浅的中性尼利诺区域; (iii)FNAL和BNL报道的MUON G-2异常可以在2- sigma水平上解释,这表明在HL-LHC上可能可以访问光sleptons和electroweakinos; (iv)W-boson质量的CDF II测量可以稍微解释,但需要在TEV附近的光站,这可能很快被LHC搜索所覆盖。

This is a brief overview on the low energy supersymmetry in light of current experiments including the LHC searches, the dark matter (DM) detections, the muon g-2 and the CDF II measurement of the W-boson mass. We focus on the minimal framework of supersymmetry, namely the minimal supersymmetric model (MSSM), and obtain the following conclusions: (i) The MSSM can survive all current experiments, albeit suffering from the little hierarchy problem due to the heavy stops pushed up by the LHC searches; (ii) The DM relic density can be readily achieved by the thermal freeze-out of the lightest neutralino and the null results of DM direct detections are typically driving the parameter space to the bino-like lightest neutralino region; (iii) The muon g-2 anomaly reported by FNAL and BNL can be explained at 2-sigma level, which indicates light sleptons and electroweakinos possibly accessible at the HL-LHC; (iv) The CDF II measurement of the W-boson mass can be marginally explained, but requires light stops near TeV which may soon be covered by the LHC searches.
