希格西诺暗物质的谨慎魅力-袖珍评论
The discreet charm of higgsino dark matter - a pocket review
摘要：
本文简要评述了低尺度超对称性中希格西诺暗物质探测的局限性和前景。在第一部分中，我们认为，在进行了MSSM中所有潜在的暗物质粒子的调查后，（几乎）纯希格西诺是唯一的候选人，几乎毫发无损地从近年来的观测数据的财富。在这样做的凭借其规范量子数和电弱对称性破缺，它保持在同一时间相对较高程度的模型无关性。在第二部分中，我们适当地回顾了在直接地下暗物质搜寻、对撞机搜寻和间接天体物理信号中探测类希格斯诺中性伴子的前景。我们提供了估计的超伙伴和微调的背景下，在传统的情况下，超对称性的破缺介导的大统一的规模和强烈的期望，及时检测到希格斯玻色子在地下探测器是密切相关的测量125 GeV的质量的希格斯玻色子在大型强子对撞机。
英文摘要：
We give a brief review of the current constraints and prospects for detection of higgsino dark matter in low-scale supersymmetry. In the first part we argue, after performing a survey of all potential dark matter particles in the MSSM, that the (nearly) pure higgsino is the only candidate emerging virtually unscathed from the wealth of observational data of recent years. In doing so by virtue of its gauge quantum numbers and electroweak symmetry breaking only, it maintains at the same time a relatively high degree of model-independence. In the second part we properly review the prospects for detection of a higgsino-like neutralino in direct underground dark matter searches, collider searches, and indirect astrophysical signals. We provide estimates for the typical scale of the superpartners and fine tuning in the context of traditional scenarios where the breaking of supersymmetry is mediated at about the scale of Grand Unification and where strong expectations for a timely detection of higgsinos in underground detectors are closely related to the measured 125 GeV mass of the Higgs boson at the LHC.
