论文摘要
我们研究了暗物质结合状态的形成及其对间接检测实验的影响。我们关注的是暗物质是强耦合黑暗区域的重子，并为在发射光子发射时形成浅核结合状态以及W和Z量规玻色子提供了通用公式。这些过程可以通过电气和磁性转变发生，并产生间接信号，这些信号可通过费米和HESS进行单色和弥漫性光子测量。我们还研究将边界形成横截面分解成短途核部分的有效性乘以Sommerfeld增强因子。我们发现，短距离核电位通常会违反分解，特别是对与零能量结合状态相关的峰的位置进行了修改。最后，我们重新审视了（弱耦合）最小的DM Quintuplet的结合状态形成，其中包括破坏同源的效应，并发现它引起了与当前边界兼容的间接检测信号。
We investigate dark matter bound-state formation and its implication for indirect-detection experiments. We focus on the case where dark matter is a baryon of a strongly-coupled dark sector and provide generic formulae for the formation of shallow nuclear bound states on emission of photons, and W and Z gauge bosons. These processes can occur via electric and magnetic transitions, and give rise to indirect signals that are testable in monochromatic and diffuse photon measurements by Fermi and HESS. We also study the validity of factorizing the bound-state formation cross section into a short-distance nuclear part multiplied by Sommerfeld-enhancement factors. We find that the short-distance nuclear potential often violates factorization, modifying in particular the location of the peaks associated with zero-energy bound states. Finally we revisit bound-state formation of a (weakly-coupled) Minimal DM quintuplet including isospin-breaking effects, and find it gives rise to indirect-detection signals that are compatible with current bounds.
