标题： A Tight Connection Between Direct and Indirect Detection of Dark Matter through Higgs Portal Couplings to a Hidden Sector

摘要： 我们提出了一种标准模型的隐藏阿贝尔扩展，其中包括一个复标量作为暗物质候选者，以及一个轻标量作为暗物质粒子之间的长程力载体。 暗物质的索莫菲德增强湮灭截面解释了观测到的宇宙射线过剩。 轻标量场还导致暗物质与核子之间可能产生大的截面，因此为同时在直接和间接暗物质搜索实验中探测该模型提供了一种有趣的方式。 我们通过考虑CDMS-II排除限制以及PAMELA和FermiLAT数据来约束该模型的参数空间。 显示英文摘要

摘要： We present a hidden Abelian extension of the Standard Model including a complex scalar as a dark matter candidate and a light scalar acting as a long range force carrier between dark matter particles. The Sommerfeld enhanced annihilation cross-section of the dark matter explains the observed cosmic ray excesses. The light scalar field also gives rise to potentially large cross-sections of dark matter on nucleon, therefore providing an interesting way to probe this model simultaneously at direct and indirect dark matter search experiments. We constrain the parameter-space of the model by taking into account CDMS-II exclusion limit as well as PAMELA and FermiLAT data.
