复合(非对称)暗物质的间接探测

Indirect Detection of Composite (Asymmetric) Dark Matter

Rakhi Mahbubani, Michele Redi, Andrea Tesi

摘要:

暗物质可以在发射出等于束缚能的能量量子时形成束缚态。对于强相互作用的暗物质来说,这个过程的速率很大,并且通过长距离效应进一步增强。所得到的单色和漫射$γ$ -射线可以在间接检测实验中进行测试。如果暗物质具有电弱电荷,则间接信号包括质量在TeV范围内的多个可观测光子线。否则,如果它只通过暗光子入口耦合,来自矮星系和CMB再电离的漫反射谱为低于TeV的质量设定了强大的限制。这种机制提供了一个强大的手段,探测不对称暗物质今天。

英文摘要:

Dark Matter can form bound states upon the emission of quanta of energy equal to the binding energy. The rate of this process is large for strongly-interacting Dark Matter, and further enhanced by long distance effects. The resulting monochromatic and diffuse $γ$-rays can be tested in indirect detection experiments. If Dark Matter has electroweak charge, indirect signals include multiple observable photon lines for masses in the TeV range. Else if it couples only via a dark photon portal, diffuse spectra from dwarf galaxies and CMB reionization set powerful limits for masses below a TeV. This mechanism provides a powerful means of probing Asymmetric Dark Matter today.
