摘要

跷跷板II型机制是在一个具有规范群\(SU{{(2)}_{L}} \times SU{{(2)}_{R}} \times U(1)\)的左右手性模型的框架内考虑的，该模型的轻子扇区包括三代重马约拉纳中微子。分析了在活动中微子质量正、逆层次情况下，作为暗物质粒子的最轻惰性中微子的混合参数在左右对称破缺尺度上的依赖关系。

Dark Matter Mixing within the Seesaw Type II Mechanism in the Left-Right Symmetric Model

The seesaw type II mechanism is considered within the framework of a left-right chiral model with a gauge group \(SU{{(2)}_{L}} \times SU{{(2)}_{R}} \times U(1)\), the lepton sector of which includes three generations of heavy Majorana neutrinos. The dependence of the mixing parameters of the lightest sterile neutrino as a dark matter particle on the scales of left-right symmetry breaking in the case of direct and inverse hierarchies of active neutrino masses is analyzed.
