论文摘要
我们探索具有光中性的热暗物质（$ m _ {\tildeχ_1^0} \ leq m_h/2 $），探索现象学最小超对称标准模型（PMSSM）的参数空间，与当前的碰撞器和天体物理约束是一致的。我们考虑了希格斯诺质量参数的正值和负值（$μ$）。我们的调查表明，LHC的最新实验结果以及Lux-Zeplin（LZ）协作对暗物质的直接检测搜索规则，规定了$ z $ -Funnel区域，$μ> 0 $> 0 $方案。相同的结果严重限制了$ h $ funnel区域的正$ $ $，但是，可以通过LZ实验的几天数据轻松探测允许点。在$μ<0 $方案中，我们发现$ z $和$ h $ funnels中的非常轻的希格斯诺斯可能会在LHC的electroweakino搜索中幸存下来，而实验协作中的付出的努力对于就其当前状态做出了结论性的陈述所必需。
We explore the parameter space of the phenomenological Minimal Supersymmetric Standard Model (pMSSM) with a light neutralino thermal dark matter ($m_{\tildeχ_1^0} \leq m_h/2$) that is consistent with current collider and astrophysical constraints. We consider both positive and negative values of the higgsino mass parameter ($μ$). Our investigation shows that the recent experimental results from the LHC as well as from direct detection searches for dark matter by the LUX-ZEPLIN (LZ) collaboration rule out the $Z$-funnel region for the $μ>0$ scenario. The same results severely restrict the $h$-funnel region for positive $μ$, however, the allowed points can be probed easily with few more days of data from the LZ experiment. In the $μ<0$ scenario, we find that very light higgsinos in both the $Z$ and $h$ funnels might survive the present constraints from the electroweakino searches at the LHC, and dedicated efforts from experimental collaborations are necessary to make conclusive statements about their present status.
