论文摘要

假设最轻的中性诺是最轻的超对称性(SUSY)粒子的最小超对称标准模型(MSSM)的电动性超对称标准模型(MSSM)可以说明各种实验数据:由于其小型生产截面的相互限制(较高的),该extription(SUSY)粒子是最小的搜索(lhc搜索),该结果是相互限制的(较高的),该结果(高度)的结果(较高的),该景点是较小的(高度)的结果。直接检测(DD)极限。这样的光EW部门可以特别解释$(G-2)_ $的实验结果之间的加固$ 4.2 \,σ$差异,其标准模型(SM)预测。使用改进的$(G-2)_μ$的限制,我们回顾了DD实验未来前景的预测。该分析是针对MSSM中DM的几种不同实现进行的:Bino,Bino/Wino,Wino和Higgsino DM。我们发现Higgsino,Wino和一种类型的Bino场景可以通过未来的DD实验涵盖。混合的Bino/Wino和另一种类型的Bino DM可以到达中微子地板下方的DD横截面。在这些情况下,未来的对撞机实验必须涵盖其余参数空间。

An electroweak (EW) sector of the Minimal Supersymmetric Standard Model (MSSM) with masses of a few hundred GeV can account for variety of experimental data, assuming the lightest neutralino to be the lightest supersymmetric (SUSY) particle: the non-observation at the LHC searches owing to their small production cross sections, the results for the (upper limit of the) Dark Matter (DM) relic abundance and the DM Direct Detection (DD) limits. Such a light EW sector can in particular explain the reinforced $4.2\,σ$ discrepancy between the experimental result for $(g-2)_μ$, and its Standard Model (SM) prediction. Using the improved limits on $(g-2)_μ$, we review the predictions for the future prospects of the DD experiments. This analysis is performed for several different realizations of DM in the MSSM: bino, bino/wino, wino and higgsino DM. We find that higgsino, wino and one type of bino scenario can be covered by future DD experiments. Mixed bino/wino and another type of bino DM can reach DD cross sections below the neutrino floor. In these cases future collider experiments must cover the remaining parameter space.
