论文摘要
暗物质与标准模型之间的最强相互作用可能发生通过中微子部门。与伽玛射线和带电的颗粒不同,中微子为探测暗物质的天体物理来源提供了独特的途径,因为它们不受阻碍地从其来源到达。以前,我们向中微子报道了暗物质的歼灭。在这里,我们回顾了从MEV到ZEV的一系列暗物质质量中对暗物质衰变的限制,汇总了先前报道的限制,探索了新的Electroweak校正和计算限制,但以前没有计算出来。我们检查了在当前和即将进行的中微子实验中对中微子通量的预期贡献,以及在伽马射线望远镜上预期的Electroweak排放中的光子,导致对暗物质衰减寿命的限制,范围从$τ\ sim 1.2 \ sim 1.2 \ times10^{21} $ s at 10〜mev at $ 1.5 mev to $ 1.5^peev t of time 10^29.
It is possible that the strongest interactions between dark matter and the Standard Model occur via the neutrino sector. Unlike gamma rays and charged particles, neutrinos provide a unique avenue to probe for astrophysical sources of dark matter, since they arrive unimpeded and undeflected from their sources. Previously, we reported on annihilations of dark matter to neutrinos; here, we review constraints on the decay of dark matter into neutrinos over a range of dark matter masses from MeV to ZeV, compiling previously reported limits, exploring new electroweak corrections and computing constraints where none have been computed before. We examine the expected contributions to the neutrino flux at current and upcoming neutrino experiments as well as photons from electroweak emission expected at gamma-ray telescopes, leading to constraints on the dark matter decay lifetime, which ranges from $τ\sim 1.2\times10^{21}$ s at 10~MeV to $1.5\times10^{29}$~s at 1~PeV.
