论文摘要
我们计算深色物质（DM）的衰变光谱，其质量超过了电动对称性破裂的尺度，一直到普朗克尺度。对于涉及对不间断标准模型的衰减的任意硬过程，我们确定稳定状态的迅速分布，包括光子，中微子，正面子和抗抗脂蛋白。这些光谱是通过在最高能量的间接检测中搜索DM的关键成分，因为在当前和即将进行的实验中进行了探测，包括Icecube，HAWC，CTA和LHAASO。我们的方法在现有方法上大大提高。例如，我们包括所有相关的电子相互作用。这些效果随着DM质量的增长而增长，通过EEV，我们的光谱可能因现有结果的数量级而有所不同。
We compute the decay spectrum for dark matter (DM) with masses above the scale of electroweak symmetry breaking, all the way to the Planck scale. For an arbitrary hard process involving a decay to the unbroken standard model, we determine the prompt distribution of stable states including photons, neutrinos, positrons, and antiprotons. These spectra are a crucial ingredient in the search for DM via indirect detection at the highest energies as being probed in current and upcoming experiments including IceCube, HAWC, CTA, and LHAASO. Our approach improves considerably on existing methods. For example, we include all relevant electroweak interactions. The importance of these effects grow with DM mass, and by an EeV our spectra can differ by orders of magnitude from existing results.
