超新星遗迹电子中微子和反中微子在未来大型天文台中的应用

Supernova Relic Electron Neutrinos and anti-Neutrinos in future Large-scale Observatories

C. Volpe, J. Welzel

摘要:

本文研究了正在研究中的MEMPHYS(UNO,Hyper-K)、LENA和GLACIER等未来大型天文台的超新星遗迹中微子信号。本文讨论了利用质子散射和利用氧、碳、氩等原子核散射观测超新星遗迹电子反中微子和中微子的互补信息。在确定残余中微子通量时,我们还首次考虑了中微子磁矩与核心坍缩超新星内部磁场的耦合。我们提出的数值结果的遗迹电子中微子和反中微子通量和事件的数量上的电子中微子的碳,氧和氩,以及电子反中微子的质子,各种振荡的情况。超新星遗迹中微子的观测可能为我们提供关于核心坍缩超新星爆炸、恒星形成历史和中微子性质的独特信息,这些信息仍然是未知的。

英文摘要:

We investigate the signal from supernova relic neutrinos in future large scale observatories, such as MEMPHYS (UNO, Hyper-K), LENA and GLACIER, at present under study. We discuss that complementary information might be gained from the observation of supernova relic electron anti-neutrinos and neutrinos using the scattering on protons on one hand, and on nuclei such as oxygen, carbon or argon on the other hand. When determining the relic neutrino fluxes we also include, for the first time, the coupling of the neutrino magnetic moment to magnetic fields within the core-collapse supernova. We present numerical results on both the relic electron neutrino and anti-neutrino fluxes and on the number of events for electron neutrinos on carbon, oxygen and argon, as well as electron anti-neutrinos on protons, for various oscillation scenarios. The observation of supernova relic neutrinos might provide us with unique information on core-collapse supernova explosions, on the star formation history and on neutrino properties, that still remain unknown.
