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 $\chi$aro$\nu$, a software package that, in the spirit of its mythological Greek namesake $\chi \acute\alpha \rho \omega \nu $, 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 $\chi$aro$\nu$ or is taken from user supplied tables. $\chi$aro$\nu$ then propagates this flux through vacuum or dense media and returns the expected neutrino yield at an observer's location. In developing $\chi$aro$\nu$, 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.

χaroν:用于从 WIMP 生成中微子通量的工具

已经使用所有宇宙信使:伽马射线、宇宙射线和中微子,对微粒暗物质的特征进行了间接搜索。从中微子中寻找暗物质尤为重要,因为它们是唯一可以从密集环境(例如太阳或地球的核心)或可观测宇宙边缘的暗物质过程中到达探测器的信使。在这项工作中,我们介绍了 $\chi$aro$\nu$,这是一个软件包,本着其神话希腊同名 $\chi \acute\alpha \rho \omega \nu $ 的精神,在黑暗部门和标准之间架起了桥梁通过预测来自不同天体暗物质团聚体的中微子通量进行建模。生产点的通量要么由 $\chi$aro$\nu$ 内部计算,要么从用户提供的表格中获取。$\chi$aro$\nu$ 然后通过真空或致密介质传播该通量,并返回观察者所在位置的预期中微子产量。在开发 $\chi$aro$\nu$ 的过程中,我们重新审视和更新了稠密介质中中微子的产生,更新了高能中微子的传播,并研究了中微子传输不确定性的来源。该软件包与新的计算相结合,其中包括电弱校正,导致来自地球、太阳的能量范围为 1 GeV 到 10 PeV 的暗物质衰变和湮灭产生的中微子通量的最新和完整存储库,以及银河光环。更新了高能中微子的传播,研究了中微子传输的不确定性来源。该软件包与新的计算相结合,其中包括电弱校正,导致来自地球、太阳的能量范围为 1 GeV 到 10 PeV 的暗物质衰变和湮灭产生的中微子通量的最新和完整存储库,以及银河光环。更新了高能中微子的传播,研究了中微子传输的不确定性来源。该软件包与新的计算相结合,其中包括电弱校正,导致来自地球、太阳的能量范围为 1 GeV 到 10 PeV 的暗物质衰变和湮灭产生的中微子通量的最新和完整存储库,以及银河光环。
