论文摘要
在超新星的光环中，有一种公认的方法来计算中微子风味密度矩阵，其中中微子振幅而不是跨剖面需要在频繁散射区域上方的区域中仔细遵循。相同的推理和技术适用于中微子解耦时代早期宇宙中中微子风味和能量分布的演变，从而导致了中微子 - 中微子中性抗体相互作用的影响的根本变化。 如果存在的无菌中微子的生产预测也将改变。
There is an accepted approach to calculation of the neutrino flavor density-matrix in the halo of a supernova, in which neutrino amplitudes, not cross-sections, need to be followed carefully in the region above the region of frequent scatterings. The same reasoning and techniques, applied to the evolution of neutrino flavors and energy distributions in the early universe in the era of neutrino decoupling, leads to radical changes in the prediction of the effects of the neutrino-neutrino interaction. Predictions for the production of sterile neutrinos, should they exist, will also be changed.
