寻找地外高能中微子

In Search for Extraterrestrial High Energy Neutrinos

Luis A. Anchordoqui, Teresa Montaruli

摘要:

本文综述了天体物理中微子的研究进展。我们首先总结了各种理论预测,这些预测将预期的中微子通量与其他信使的数据相关联,特别是伽马射线和超高能宇宙射线。然后,我们回顾了中微子望远镜的运行和退役的状态和结果,用于数据分析和背景判别的方法。特别注意的是,高度不确定的大气μ介子和中微子背景的扩散中微子通量的搜索所面临的挑战。接下来,我们将研究中微子通量的现有限制对宇宙射线化学成分研究的影响。在此之后,我们表明,不仅中微子有可能发现天体物理源,但大气μ子的巨大统计数据也可以是一个强大的工具。最后,我们讨论了用中微子望远镜间接探测暗物质的前景。

英文摘要:

In this paper we review the search for astrophysical neutrinos. We begin by summarizing the various theoretical predictions which correlate the expected neutrino flux with data from other messengers, specifically gammas and ultra-high energy cosmic rays. We then review the status and results of neutrino telescopes in operation and decommissioned, the methods used for data analysis and background discrimination. Particular attention is devoted to the challenge enforced by the highly uncertain atmospheric muon and neutrino backgrounds in relation to searches of diffuse neutrino fluxes. Next, we examine the impact of existing limits on neutrino fluxes on studies of the chemical composition of cosmic rays. After that, we show that not only do neutrinos have the potential to discover astrophysical sources, but the huge statistics of atmospheric muons can be a powerful tool as well. We end by discussing the prospects for indirect detection of dark matter with neutrino telescopes.
