论文摘要
核心偏离超新星中的中微子可以进行快速的风味转化，并可能影响爆炸机制和核合成。在存在三种中微子的情况下，我们对快速转化进行了第一个非线性模拟。最近使用MUON生产的超新星模拟要求进行这种分析，因为它们放宽了标准$ν_{μ，τ} = \barν_{μ，τ} $（两种味）假设。我们的结果表明了Muon和Tau Lepton数字分布的重要性，以及传统的电子Lepton数字。的确，我们的三种培养结果可能与两种香料味有很大不同。这些结果加强了进一步研究超新星模拟数据中快速转化的发生的必要性，包括MU和TAU中微子的退化性破坏。
Neutrinos in a core-collapse supernova can undergo fast flavor conversions with a possible impact on the explosion mechanism and nucleosynthesis. We perform the first non-linear simulations of fast conversions in the presence of three neutrino flavors. The recent supernova simulations with muon production call for such an analysis, as they relax the standard $ν_{μ,τ}=\barν_{μ,τ}$ (two-flavor) assumption. Our results show the significance of muon and tau lepton number angular distributions, together with the traditional electron lepton number ones. Indeed, our three-flavor results are potentially very different from two-flavor ones. These results strengthen the need to further investigate the occurrence of fast conversions in supernova simulation data, including the degeneracy breaking of mu and tau neutrinos.
