用慢液体scintillator探测器发现超新星遗迹中微子的可能性

Hanyu Wei, Zhe Wang, Shaomin Chen

摘要:

超新星遗迹中微子的探测可以为我们目前对恒星和宇宙演化的理解提供关键支持,对这些中微子的精确测量可以产生对宇宙的新见解。本文研究了使用线性烷基苯(LAB)作为慢液体闪烁体探测超新星遗迹中微子的潜力。直链烷基苯具有良好的Cherenkov和闪烁光分离特性,为颗粒物的识别提供了一条新的途径。我们进一步讨论了当前实验中的关键问题,包括(1)水切伦科夫探测器中大气中微子的带电电流本底和(2)典型液体闪烁体探测器中大气中微子的中性电流本底。锦屏的千吨级LAB探测器拥有$\mathcal{O}$(10)年的数据,可以发现超新星遗迹中微子,其灵敏度与大容量水切伦科夫探测器、典型的液体闪烁体探测器和液氩探测器相当。

英文摘要:

Detection of supernova relic neutrinos could provide key support for our current understanding of stellar and cosmological evolution, and precise measurements of these neutrinos could yield novel insights into the universe. In this paper, we studied the detection potential of supernova relic neutrinos using linear alkyl benzene (LAB) as a slow liquid scintillator. The linear alkyl benzene features good separation of Cherenkov and scintillation lights, thereby providing a new route for particle identification. We further addressed key issues in current experiments, including (1) the charged current background of atmospheric neutrinos in water Cherenkov detectors and (2) the neutral current background of atmospheric neutrinos in typical liquid scintillator detectors. A kiloton-scale LAB detector at Jinping with $\mathcal{O}$(10) years of data could discover supernova relic neutrinos with a sensitivity comparable to that of large-volume water Cherenkov detectors, typical liquid scintillator detectors, and liquid argon detectors.
