摘要:

本文探讨核坍缩超新星作为中微子望远镜的关键目标,解决其模拟结果中的不确定性。我们全面分析了18个现代模拟,并利用现实探测器和相互作用区分超新星模型。发现总中微子能量与累积计数间存在显著相关性,该相关性由大质量轻子中微子和振荡驱动,在DUNE探测器中尤为明显。贝叶斯技术表明银河系超新星事件期间具有强大的模型区分潜力,HK在基于状态方程、前身星质量和混合方案区分模型方面表现卓越。

英文摘要:

This paper explores core-collapse supernovae as crucial targets for neutrino telescopes, addressing uncertainties in their simulation results. We comprehensively analyze eighteen modern simulations and discriminate among supernova models using realistic detectors and interactions. A significant correlation between the total neutrino energy and cumulative counts, driven by massive lepton neutrinos and oscillations, is identified, particularly noticeable with the DUNE detector. Bayesian techniques indicate strong potential for model differentiation during a Galactic supernova event, with HK excelling in distinguishing models based on equation of state, progenitor mass, and mixing scheme.
