论文摘要
使用分析治疗,我们讨论了大型活性 - 菌群中微子混合角的参数区域,在这些中微子中中微子在非共振风味振荡中产生的无菌中微子可以在几种宇宙学中接近热化。我们表明,热化仅影响已经被不同限制拒绝的大型活动中微子混合。因此,允许的无菌中微子参数区域不受影响。
Using an analytic treatment, we discuss the parameter regions of large active-sterile neutrino mixing angles where sterile neutrinos produced in non-resonant flavour oscillations can approach thermalization in several cosmologies. We show that thermalization affects only large active-sterile neutrino mixing already rejected by different limits. Hence, the allowed sterile neutrino parameter regions are unaffected.
