论文摘要
在本演讲中，我们讨论了由暗物质（DM）歼灭或衰减引起的颗粒光谱的物理模型。在DM间接搜索的背景下，最终的状态产品通常将经历一系列复杂的过程，例如共振衰减，QED/QCD辐射，强调和强子衰变。这组过程导致稳定的颗粒（光子，正电子，抗蛋白酶和中微子等）在到达检测器之前长距离行驶。它们的光谱建模包含一些不确定性，这些不确定性在相关分析中经常被忽略。我们讨论了这些不确定性的来源，并估计了它们对[10，1000] \，$ gev中$m_χ\基准DM方案的光子能量光谱的影响。还提供了如何从Zenodo检索完整表的说明。
In this talk, we discuss the physics modelling of particle spectra arising from dark matter (DM) annihilation or decay. In the context of the indirect searches of DM, the final state products will, in general, undergo a set of complicated processes such as resonance decays, QED/QCD radiation, hadronisation and hadron decays. This set of processes lead to stable particles (photons, positrons, anti-protons, and neutrinos among others) which travel for very long distances before reaching the detectors. The modelling of their spectra contains some uncertainties which are often neglected in the relevant analyses. We discuss the sources of these uncertainties and estimate their impact on photon energy spectra for benchmark DM scenarios with $m_χ\in [10, 1000]\,$GeV. Instructions for how to retrieve complete tables from Zenodo are also provided.
