论文摘要

使用所有宇宙信使:伽玛射线,宇宙射线和中微子进行了间接搜索有关红血暗物质的签名的间接搜索。从中微子那里寻找暗物质是尤其重要的,因为它们是唯一可以从密集环境(例如太阳或地球的核心,或可观察到的宇宙边缘)中从暗物质过程中传达出探测器的唯一快递员。在这项工作中,我们介绍了$χ$ ARO $ν$,该软件包本身以其神话般的希腊同名同名$χ\acuteαρων$,通过预测来自不同天体暗物质的不同中微子通量来桥接黑暗扇区和标准模型。生产点的通量要么在内部通过$χ$ aro $ν$计算,要么是从用户提供的表中获取的。 $χ$ ARO $ν$然后通过真空或致密媒体传播这种通量,并在观察者的位置返回预期的中微子产量。在开发$χ$ ARO $ν$时,我们已经重新审视并更新了中微子在密集的媒体中的生产,更新了高能中微子的传播,并研究了中微子运输中不确定性的来源。该软件包与新的计算相结合,该计算包括电动校正,从而在1 GEV到10 GEV到10 PEV的中微子通量的最新和完整的中微子通量库中,来自地球,太阳,太阳和银河系的光环。

Indirect searches for signatures of corpuscular dark matter have been performed using all cosmic messengers: gamma rays, cosmic rays, and neutrinos. The search for dark matter from neutrinos is of particular importance since they are the only courier that can reach detectors from dark matter processes in dense environments, such as the core of the Sun or Earth, or from the edge of the observable Universe. In this work, we introduce $χ$aro$ν$, a software package that, in the spirit of its mythological Greek namesake $χ\acuteαρων$, bridges the dark sector and Standard Model by predicting neutrino fluxes from different celestial dark matter agglomerations. The flux at the point of production is either computed internally by $χ$aro$ν$ or is taken from user supplied tables. $χ$aro$ν$ then propagates this flux through vacuum or dense media and returns the expected neutrino yield at an observer's location. In developing $χ$aro$ν$, we have revisited and updated the production of neutrinos in dense media, updated the propagation of high-energy neutrinos, and studied the sources of uncertainty in neutrino transport. This package is coupled to a new calculation that includes electroweak corrections resulting in the most up-to-date and complete repository of neutrino fluxes from dark matter decay and annihilation over the energy range of 1 GeV to 10 PeV coming from the Earth, the Sun, and the Galactic halo.
