论文摘要
Darksusy是一种多功能工具，用于精确计算各种与暗物质相关的信号，从对暗物质遗物密度的预测到暗物质自我互动以及与直接和间接检测实验相关的速率。自2018年Darksusy 6发布以来，近年来，在所有这些领域中都进行了重要的新代码，我们在此概述中总结了这一点。特别是，Darksusy现在允许用户通过冷冻机制来计算微弱相互作用的大规模颗粒的遗物密度，但在存在僻静的黑暗扇区以及在冻结过程中没有完全确定动力学平衡的模型的情况下，还为冻结计算提供了新的例程。在直接检测侧，宇宙射线对暗物质的上散射的影响已经完全实现，从而导致地球预期的暗物质通量中的替代相对论组成部分。最后，已经添加了与间接搜索相关的带有伽玛射线，中微子或带电宇宙射线的收益率；新的默认频谱基于大量的Pythia 8运行，但用户也可以轻松地在各种替代光谱之间切换。在www.darksusy.org上提供了更多代码详细信息，包括手册和各种具体示例应用程序。
DarkSUSY is a versatile tool for precision calculations of a large variety of dark matter-related signals, ranging from predictions for the dark matter relic density to dark matter self-interactions and rates relevant for direct and indirect detection experiments. In all of these areas significant new code additions have been made in recent years, since the release of DarkSUSY 6 in 2018, which we summarize in this overview. In particular, DarkSUSY now allows users to compute the relic density for feebly interacting massive particles via the freeze-in mechanism, but also offers new routines for freeze-out calculations in the presence of secluded dark sectors as well as for models where kinetic equilibrium is not fully established during the freeze-out process. On the direct detection side, the effect of cosmic-ray upscattering of dark matter has been fully implemented, leading to a subdominant relativistic component in the expected dark matter flux at Earth. Finally, updated yields relevant for indirect searches with gamma rays, neutrinos or charged cosmic rays have been added; the new default spectra are based on a large number of Pythia 8 runs, but users can also easily switch between various alternative spectra. Further code details, including a manual and various concrete example applications, are provided at www.darksusy.org.
