通过Higgs门耦合直接和间接探测暗物质之间的紧密联系

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

Chiara Arina, Francois-Xavier Josse-Michaux, Narendra Sahu

摘要:

我们提出了一个隐藏的阿贝尔扩展的标准模型,包括一个复杂的标量作为暗物质的候选人和轻标量作为一个长期的暗物质粒子之间的力载体。索末菲增强湮灭截面的暗物质解释了观察到的宇宙射线过剩。轻标量场也引起潜在的大截面的暗物质的核子,因此提供了一个有趣的方式来探测这个模型同时在直接和间接的暗物质搜索实验。我们通过考虑CDMS-II排除限制以及PAMELA和FermiLAT数据来约束模型的参数空间。

英文摘要:

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.
