Abstract

The upcoming galactic core-collapse supernova is expected to produce a considerable number of neutrino events within terrestrial detectors. By using Bayesian inference techniques, we address the feasibility of distinguishing among various neutrino flavor conversion scenarios in the supernova environment, using such a neutrino signal. In addition to the conventional Mikheev-Smirnov-Wolfenstein, we explore several more sophisticated flavor conversion scenarios, such as spectral swapping, fast flavor conversions, flavor equipartition caused by nonstandard neutrino interactions, magnetically induced flavor equilibration, and flavor equilibrium resulting from slow flavor conversions. Our analysis demonstrates that with a sufficiently large number of neutrino events during the supernova accretion phase (exceeding several hundreds), there exists a good probability of distinguishing among feasible neutrino flavor conversion scenarios in the supernova environment.

即将到来的银河系核心坍缩超新星预计将在地面探测器内产生相当数量的中微子事件。通过使用贝叶斯推理技术，我们探讨了在超新星环境中利用这种中微子信号区分各种中微子味道转换情景的可行性。除了传统的米赫耶夫-斯米尔诺夫-沃尔芬斯坦（Mikheev-Smirnov-Wolfenstein）之外，我们还探索了几种更复杂的味道转换情况，如光谱交换、快速味道转换、由非标准中微子相互作用引起的味道均衡、磁诱导的味道均衡以及由慢速味道转换引起的味道均衡。我们的分析表明，在超新星吸积阶段，只要有足够多的中微子事件（超过几百个），就很有可能区分超新星环境中可行的中微子味道转换情况。美国物理学会出版 2025
