O-Ne-Mg核塌缩超新星中子化中微子爆发的味演化

摘要:

本文给出了一颗O-Ne-Mg核塌缩超新星中子化爆发的3-中微子味演化模拟结果。我们发现,非线性中微子自耦合工程师的一个单一的光谱功能的逐步转换的倒中微子质量等级的情况下,在正常的质量等级的情况下,两个这样的功能对应的真空中微子质量平方差与太阳和大气中微子振荡的叠加。这些中微子的光谱特征提供了一个独特的潜在的探测条件下的超新星环境,并可能使我们能够区分O-Ne-Mg和Fe核心塌缩超新星。

英文摘要:

We present results of 3-neutrino flavor evolution simulations for the neutronization burst from an O-Ne-Mg core-collapse supernova. We find that nonlinear neutrino self-coupling engineers a single spectral feature of stepwise conversion in the inverted neutrino mass hierarchy case and in the normal mass hierarchy case, a superposition of two such features corresponding to the vacuum neutrino mass-squared differences associated with solar and atmospheric neutrino oscillations. These neutrino spectral features offer a unique potential probe of the conditions in the supernova environment and may allow us to distinguish between O-Ne-Mg and Fe core-collapse supernovae.
