提高中微子望远镜对低能天体物理源灵敏度的多探测器方法

Multi-detector approach to enhance the sensitivity of neutrino telescopes to low-energy astrophysical sources

Gwenhaël de Wasseige

摘要:

虽然大型中微子望远镜迄今主要集中在TeV-PeV天体物理中微子的探测,但一些努力正在进行中,以将灵敏度扩展到GeV水平的瞬态源。目前只进行了少数中微子搜索,在这个能量范围内对天体物理瞬变的特征知之甚少。在这篇文章中,我们讨论了高能中微子望远镜探索GeV能量范围的动机,并总结了目前探测器的局限性,如IceCube和KM 3 NeT。然后,我们提出并比较不同的方法多探测器分析,可能会提高灵敏度的瞬态GeV中微子通量。

英文摘要:

While large neutrino telescopes have so far mainly focused on the detection of TeV-PeV astrophysical neutrinos, several efforts are ongoing to extend the sensitivity down to the GeV level for transient sources. Only a handful of neutrino searches have been carried out at the moment leaving the signature of astrophysical transients poorly known in this energy range. In this contribution, we discuss the motivations for high-energy neutrino telescopes to explore the GeV energy range and summarize the current limitations of detectors, such as IceCube and KM3NeT. We then present and compare different approaches for multi-detector analyses that may enhance the sensitivity to a transient GeV neutrino flux.
