论文摘要
我们检查了对暗物质的间接检测，将暗物质歼灭成深色胶球，进而通过一系列门户进入标准模型。如果暗物质候选人伴侣伴随着没有光口味的限制力，则会发生这种情况，这代表了许多可能的复杂黑暗部门。由于最小模型的未检测以及理论动机，例如Twin Higgs解决了小层次结构问题，因此人们越来越多地考虑了这种隐藏的山谷情景。在黑暗淋浴中建模其产量的困难，对间接检测中的黑胶球进行了研究。我们使用最近的GlueShower代码来对暗物质通过深色粘合球歼灭到光子，抗磷脂和正电子通道的标准模型中产生第一个约束。我们还适合银河中心的过度，并使用此观察结果，并结合其他天体物理约束，以显示多通道观察如何限制该理论的紫外线和IR细节，即确切的衰减门户和强丽行为。这为围栏隐藏的山谷搜索提供了独特的补充发现和诊断潜力。有趣的是，热通过nihihihihihihihihihihihihihihihihihihihihihilihihihihihihihihihihihihihihihihihihihihihihihillm {o}（10〜 \ Mathrm {gev}）$ Dark Glueballs，然后通过Twin-Higgs型decay Portal可以考虑银河系中心的过度过度，同时尊重其他约束。
We examine indirect detection of dark matter that annihilates into dark glueballs, which in turn decay into the Standard Model via a range of portals. This arises if the dark matter candidate couples to a confining gauge force without light flavours, representative of many possible complex dark sectors. Such Hidden Valley scenarios are being increasingly considered due to non-detection of minimal models as well as theoretical motivations such as the Twin Higgs solution to the little hierarchy problem. Study of dark glueballs in indirect detection has previously been hampered by the difficulty of modeling their production in dark showers. We use the recent GlueShower code to produce the first constraints on dark matter annihilating via dark glueballs into the Standard Model across photon, antiproton, and positron channels. We also fit the Galactic Centre Excess and use this observation, combined with other astrophysical constraints, to show how multi-channel observations can constrain UV and IR details of the theory, namely the exact decay portal and hadronization behaviour respectively. This provides unique complementary discovery and diagnostic potential to Hidden Valley searches at colliders. It is interesting to note that thermal WIMPs annihilating to $\mathcal{O}(10~\mathrm{GeV})$ dark glueballs and then the Standard Model via the Twin-Higgs-like decay portal can account for the Galactic Centre Excess while respecting other constraints.
