The sensitivity increase of a large Cherenkov photon detector for extremely high energy cosmogenic neutrinos

为了揭示能量在1020 eV以上的超高能宇宙线的起源，对这些超高能中微子进行探测是非常有效的。我开发了一种方法来提高大型切伦科夫光子探测器对这些中微子的灵敏度。背景大气中的Muon束和由这些中微子产生的单个Muon之间的事件看起来很相似，但我发现切伦科夫光子在运动方向上的分布是不同的。利用这种差异可以得到更多的中微子信号。

In order to reveal the origin of the extremely high energy cosmic rays (EHECRs) with the energies above 1020 eV, it is effective to detect extremely high energy neutrinos derived from those EHECRs. I developed a method to increase the sensitivity of a large Cherenkov photon detector for those neutrinos. Events between background atmospheric muon bundles and single muons derived from those neutrinos apparently look similar, however, I found that there is a difference of the Cherenkov photon distribution in the moving direction. More neutrino signals can be obtained by using the difference.
