N. Yu. Zysina, S. V. Fomichev, V. V. Khruschov

摘要:

研究了狄拉克和马约拉纳大质量中微子的基本特征。目前可用的实验数据,这些特性的证据可能超出标准模型与三个轻中微子的异常。特别注意的是如何确定中微子质量的绝对尺度。根据已有的实验数据,对中微子质量矩阵元的允许值进行了数值计算。讨论了中微子混合矩阵的质量、角度和CP破坏相之间的唯象关系,并计算了双模中微子模型的中微子质量特性和Dirac CP破坏相的值.对无菌中微子质量、中微子质量特征值和狄拉克CP破坏相的估计可用于解释和预测各种中微子实验的结果。

英文摘要:

The basic characteristics used for the description of both Dirac and Majorana massive neutrinos are studied. Currently available experimental data for these characteristics are presented with an evidence of possible anomalies beyond the Standard Model with three light neutrinos. Special attention has been paid to ways to determine the neutrino mass absolute scale. In accordance with the available data, the permissible values of the neutrino mass matrix elements are found numerically against the minimal mass of neutrino. Some phenomenological relations for the masses, the angles and the CP-violating phases of the neutrino mixing matrix are discussed, and the values of the neutrino mass characteristics and the Dirac CP-violating phase are evaluated for a model of bimodal neutrinos. The estimations made for masses of sterile neutrinos, the values of the neutrino mass characteristics and the Dirac CP-violating phase can be used for interpretation and prediction of the results of various neutrino experiments.
