中微子望远镜中μ介子束内的中微子事件

Neutrino events within muon bundles at neutrino telescopes

Miguel Gutiérrez, Gerardo Hernández-Tomé, José I. Illana, Manuel Masip

摘要:

大气中的中微子通量包括一个来自粲化强子的瞬发衰变的分量,它只有在$E\ge 10$ TeV才变得重要。然而,在这些能量下,冰立方发现的宇宙中微子的扩散通量似乎比大气中的大。在这里,我们研究了在公里级的$^3$望远镜上检测下行大气事件中中微子相互作用的可能性。中微子信号总是与μ介子束一起出现,这揭示了它的大气起源,一般来说,它意味着探测器活动随着倾斜深度的增加而增加。我们提出了一个简单的算法,可以将这些事件从常规μ子束中分离出来。

英文摘要:

The atmospheric neutrino flux includes a component from the prompt decay of charmed hadrons that becomes significant only at $E\ge 10$ TeV. At these energies, however, the diffuse flux of cosmic neutrinos discovered by IceCube seems to be larger than the atmospheric one. Here we study the possibility to detect a neutrino interaction in down-going atmospheric events at km$^3$ telescopes. The neutrino signal will always appear together with a muon bundle that reveals its atmospheric origin and, generically, it implies an increase in the detector activity with the slant depth. We propose a simple algorithm that could separate these events from regular muon bundles.
