考虑CP破坏数据的中微子混合矩阵的指数参数化

Exponential parameterization of neutrino mixing matrix with account for CP-violation data

K. Zhukovsky, F. M. Murilio

摘要:

讨论了中微子Pontecorvo-Maki-Nakagawa-Sakata混合矩阵的指数参数化。指数形式允许容易的因式分解和单独分析的CP-违反和马约拉纳条款。根据最近的中微子混合实验数据,确定了中微子指数参数化矩阵的值。导出了无CP破坏的纯转动混合部分的矩阵项。论证了夸克和中微子的互补性假说。根据最新数据和旧数据对结果进行比较。根据迄今为止不精确的实验结果,对中微子的CP破坏参数进行了估计。证明了指数参数化和CP破坏项变换的唯一性。给出了考虑CP破坏的中微子质量态矢量的指数矩阵变换。

英文摘要:

The exponential parameterization of Pontecorvo-Maki-Nakagawa-Sakata mixing matrix for neutrino is discussed. The exponential form allows easy factorization and separate analysis of the CP-violating and Majorana terms. Based upon the recent experimental data on the neutrino mixing, the values for the exponential parameterization matrix for neutrinos are determined. The matrix entries for the pure rotational part in charge of the mixing without CP-violation are derived. The complementarity hypothesis for quarks and neutrinos is demonstrated. The comparison of the results, based on most recent and on old data is held. The CP-violating parameter value is estimated, based on the so far imprecise experimental indications, regarding CP-violation for neutrinos. The unitarity of the exponential parameterisation and the CP-violating term transform is confirmed. The transform of the neutrino mass state vector by the exponential matrix with account for CP-violation is shown.
