标题： Supersymmetric Sub-Electroweak Scale Dark Matter, the Galactic Center Gamma-ray Excess, and Exotic Decays of the 125 GeV Higgs Boson

摘要： 我们继续探索共同单态扩展的最小超对称标准模型所共有的近似Peccei-Quinn对称极限。 这一极限已被确立为研究亚电弱尺度暗物质现象学的可行框架，并与新的奇异希格斯衰变物理有有趣且直接的联系。 我们提供了分析计算以激发上述重要的现象学特征。 我们还讨论了该模型框架中的基准点，这些点可以容纳观测到的银河系中心伽马射线过量。 我们强调了暗物质直接探测和间接探测现象学之间的联系，以及125 GeV希格斯玻色子的新奇异衰变通道。 我们最后识别出两种奇异希格斯衰变的基准模式，针对$h \to \tau^+ \tau^- \mbox{${\not \! E} _{\rm T}$}$ 和$h \to b \bar{b} \mbox{${\not \! E} _{\rm T}$}$ 最终态，并估计它们在大型强子对撞机上的敏感性前景。 显示英文摘要

摘要： We continue our exploration of the nearly Peccei-Quinn symmetric limit shared by common singlet extensions of the Minimal Supersymmetric Standard Model. This limit has been established as a viable framework for studying sub-electroweak scale dark matter phenomenology and has interesting and direct connections to new exotic Higgs decay physics. We present analytic calculations to motivate the important phenomenological features mentioned above. We also discuss benchmark points in this model framework that accommodate the observed Galactic Center gamma ray excess. We emphasize connections between phenomenology of dark matter direct detection and indirect detection, and new exotic decay channels for the 125 GeV Higgs boson. We conclude by identifying two benchmark modes of exotic Higgs decays for $h \to \tau^+ \tau^- \mbox{${\not\! E}_{\rm T}$}$ and $h \to b \bar{b} \mbox{${\not\! E}_{\rm T}$}$ final states and estimate their sensitivity prospects at the LHC.
