具有轻、keV和重中微子的左右SU(3)(L)xSU(3)(R)xU(1)(X)模型

摘要:

基于$SU(3)_{L}\otimes SU(3)_{R}\otimes U(1)_{X}$规范对称性,我们构造了一个完全的左右电弱相互作用模型。该模型的费米子内容是这样的异常取消限制家庭的数量是三的倍数。该模型最重要的特征之一是同时存在三个轻的活动中微子、三个keV质量级的额外中微子和六个质量在\textbf{$10^{11}$} GeV左右的重中微子。他们形成了一个很好的动机频谱的一部分,在这个意义上,他们解决了具有挑战性的问题有关的中微子振荡,温暖的暗物质,重子通过leptogenesis。

英文摘要:

We construct a full left-right model for the electroweak interactions based on the $SU(3)_{L}\otimes SU(3)_{R}\otimes U(1)_{X}$ gauge symmetry. The fermion content of the model is such that anomaly cancellation restricts the number of families to be a multiple of three. One of the most important features of the model is the joint presence of three light active neutrinos, three additional neutrinos at keV mass scale, and six heavy ones with masses around\textbf{$10^{11}$} GeV. They form a well-motivated part of the spectrum in the sense they address challenging problems related to neutrino oscillation, warm dark matter, and baryogenesis through leptogenesis.
