论文摘要
高能宇宙中微子通量的发现为中微子天文学领域铺平了道路。对于大部分通量，这些消息来源仍然不明。在地中海正在建造的KM3NET探测器旨在确定其起源。 KM3NET将用光电塑料管来仪器一公里的海水，该海水从中微子相互作用的产物中检测出具有纳秒精度的Cherenkov辐射。对于单个级联事件的特征，KM3NET已经表明它可以达到学位级别的分辨率，从而大大增加了这些中微子用于天文学的使用。在这项贡献中，我们通过制作更详细的中微子事件模型，并包括有关热门时间的其他信息，进一步完善级联重建。光的到达时间可用于改善tau中微子的双级联信号的识别，以及单个和双级联信号的角度分辨率。在两种情况下，都可以实现次级分辨率。
The discovery of a high-energy cosmic neutrino flux has paved the way for the field of neutrino astronomy. For a large part of the flux, the sources remain unidentified. The KM3NeT detector, which is under construction in the Mediterranean sea, is designed to determine their origin. KM3NeT will instrument a cubic kilometre of seawater with photomultiplier tubes that detect Cherenkov radiation from neutrino interaction products with nanosecond precision. For single cascade event signatures, KM3NeT already showed that it can reach degree-level resolutions, greatly increasing the use of these neutrinos for astronomy. In this contribution, we further refine the cascade reconstruction by making a more detailed model of the neutrinos events and including additional information on the hit times. The arrival time of light can be used to improve the identification of double cascade signatures from tau neutrinos, and the angular resolution of both single and double cascade signatures. Sub-degree resolution is achieved in both cases.
