本文在高尺度超对称模型下研究了轻子区的CP破坏以及中微子物理的其它方面。除了中微子真空期望值（VEVs），重矢量类三重态也对中微子质量有贡献。被认为是相关领域，复杂的耦合，和Zino质量的VEVs的相位。中微子质量m（nu 1）和m（nu 2）的近似简并性可以自然地理解。中微子的质量是正常的，类似于0.020 eV，0.022 eV和0.054 eV。中微子振荡中的大CP破坏是有利的。电子中微子的有效马约拉纳质量约为0.02 eV。
CP violation in the lepton sector, and other aspects of neutrino physics, are studied within a high scale supersymmetry model. In addition to the sneutrino vacuum expectation values (VEVs), the heavy vector-like triplet also contributes to neutrino masses. Phases of the VEVs of relevant fields, complex couplings, and Zino mass are considered. The approximate degeneracy of neutrino masses m(nu 1) and m(nu 2) can be naturally understood. The neutrino masses are then normal ordered, similar to 0.020 eV, 0.022 eV, and 0.054 eV. Large CP violation in neutrino oscillations is favored. The effective Majorana mass of the electron neutrino is about 0.02 eV.
