摘要
在超新星晕中计算中微子味密度矩阵有一种被广泛接受的方法,其中在中微子振幅而非截面需要于频繁散射区域之上的区域被仔细追踪。相同的推理与技术,应用于早期宇宙中微子退耦时期中微子味与能量分布的演化,导致对中微子-中微子相互作用效应的预测发生根本性改变。对于 Sterile中微子(若存在)产生的预测也将被改变。

备注
Similar to withdrawn 2011.05456, but with second example now calculated correctly. Title changed with "refractive" replaced by "collective", because non-specialists were interpreting it incorrectly. 5 pages, 2 figures. arXiv admin note: text overlap with arXiv:2011.05456
