论文摘要
下微中微子望远镜的下微子望远镜将以前所未有的敏感性在检测中微子时。在这里，我们研究了大规模中微子望远镜的功能，例如在不久的将来的全部运行的KM3NET实验，用于检测银河系中心的暗物质歼灭信号。我们考虑了Orca和Arca探测器，涵盖了从几个GEV到100 TEV的暗物质质量。我们以最大样本分析方法获得敏感性，并将其作为热平均歼灭横截面中的上限呈现为标准模型费米子。我们的预测表明，这种中微子望远镜的敏感性可以以$m_χ×gtrsim 1 \，{\ rm tev} $以及$m_χ\ simeq $少数GEV的敏感性，用于NFW暗物质密度曲线。这表明，逆戟鲸和ARCA样检测器将能够在各种群众中进行竞争性的暗物质搜索。这些引人注目的投影的含义是在一些选定的暗物质粒子模型中研究的，我们表明中微子望远镜能够探测新的参数空间。
The next generation of neutrino telescopes will feature unprecedented sensitivities in the detection of neutrinos. Here we study the capabilities of a large-scale neutrino telescope, like the fully-operating KM3NeT experiment in the near future, for detecting dark matter annihilation signals from the Galactic Centre. We consider both ORCA and ARCA detectors, covering dark matter masses from a few GeV to 100 TeV. We obtain the sensitivities with a maximum-likelihood analysis method and present them as upper limits in the thermally averaged annihilation cross-section into Standard Model fermions. Our projections show that the sensitivity of such a neutrino telescope can reach the thermal relic line for $m_χ\gtrsim 1\,{\rm TeV}$ and for $m_χ\simeq$ few GeV, for the NFW dark matter density profile. This demonstrates that ORCA- and ARCA-like detectors will be able to perform competitive dark matter searches in a wide range of masses. The implications of these striking projections are investigated in a few selected dark matter particle models, where we show that neutrino telescopes are able to probe new parameter space.
