论文摘要
在密集的超新星环境中，中微子可以经历快速的风味转化，这取决于大型中微子 - 中微子的相互作用强度。最近已经表明，从常用的三种中微子物种方法传递到具有六种物种的更一般的中微子物种方法时，它们的存在和结果都可能受到影响。在这里，我们建立了以前在该主题上执行的工作，并假设有六种中微子物种对时空中的风味演变进行数值模拟。我们发现，即使在时空的风味演变中，我们先前工作中提出的结果也保持不变。这强调了在研究快速风味转化时，需要超越三个物种的简单近似。
In the dense supernova environment, neutrinos can undergo fast flavor conversions which depend on the large neutrino-neutrino interaction strength. It has been recently shown that both their presence and outcome can be affected when passing from the commonly used three neutrino species approach to the more general one with six species. Here, we build up on a previous work performed on this topic and perform a numerical simulation of flavor evolution in both space and time, assuming six neutrino species. We find that the results presented in our previous work remain qualitatively the same even for flavor evolution in space and time. This emphasizes the need for going beyond the simplistic approximation with three species when studying fast flavor conversions.
