V. V. Khruschov, S. V. Fomichev

AI总结:

本文研究质量约1 eV的轻惰性中微子与活跃中微子混合对电子和缪子中微子振荡、β衰变及无中微子双β衰变过程的影响,基于三活跃三惰性模型估计混合参数,并考虑两种质量分布,为实验数据解释和预测提供依据。

摘要:

如果存在,具有不同质量的惰性中微子可能参与天体物理和宇宙学过程,包括与活跃中微子的混合。本文考虑了质量量级为1 eV或更小的活跃与惰性中微子混合的可能效应。对于涉及电子中微子和缪子中微子的振荡过程,以及β衰变和无中微子双β衰变过程,计算了轻惰性中微子对这些过程特性的贡献。为此,在考虑实验数据的基础上,对具有三个活跃和三个惰性中微子的模型中的混合参数进行了估计。详细讨论了惰性中微子质量分布的两种情况。所得结果可用于解释现有实验数据,也可用于预测后续实验结果。

英文摘要:

Sterile neutrinos with various masses could be participated in astrophysical and cosmological processes including mixing with active neutrinos, if exist. It is considered the possible effects of mixing of active and sterile neutrinos with masses of the order or less than 1 eV. For oscillation processes involving electron and muon neutrinos, as well as for beta decay and neutrinoless double beta decay processes, the contributions of light sterile neutrinos in the characteristics of these processes are calculated. For this purpose the estimates of the mixing parameters in the model with three active and three sterile neutrinos are made taking into account experimental data. Two cases of sterile neutrinos masses distribution are considered in detail. The results obtained can be used for interpretation of available experimental data, and also for predictions of subsequent experimental results.
