摘要
在超新星晕中计算中微子味密度矩阵有一种公认的方法,该方法要求在频繁散射区域上方的区域仔细追踪中微子振幅而非截面。将同样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,会导致对中微子-中微子相互作用效应预测的彻底改变。若存在惰性中微子,其产生量的预测也将随之改变。

备注
The equations and fig. 1 are right, but there are big complexities in their solutions that make the general effects questionable for the moment, and make part of the commentary wrong as well
