3-3-1模型中的中微子质量机制

Neutrino mass mechanisms in 3-3-1 models: A short review

C. A. de S. Pires

摘要:

本文综述了在3-3-1规范模型框架下不含奇异轻子的轻中微子产生机制。关于最小的3-3-1模型,我们提请注意的事实,该模型的微扰制度,直到5 TeV。这需要替代机制来产生轻中微子。本文在最小3-3-1模型的框架下讨论了两种产生轻中微子的机制。关于右手中微子的3-3-1模型,我们提请注意这样一个事实,即在它的机制,产生轻左手中微子也产生轻右手中微子。最后,我们提请注意这样一个事实,即右手中微子的3-3-1模型自然地容纳了逆跷跷板机制。

英文摘要:

In this paper we review some mechanisms that provide light neutrinos in the framework of 3-3-1 gauge models without exotic leptons. In regard to the minimal 3-3-1 model, we call the attention to the fact that the perturbative regime of the model goes until 5 TeV. This requires alternative mechanisms in order to generate light neutrinos. In this review we discuss two mechanisms capable of generating light neutrinos in the framework of the minimal 3-3-1 model. In regard to the 3-3-1 model with right-handed neutrinos, we call the attention to the fact that in it mechanisms that generate light left-handed neutrinos also generate light right-handed neutrinos. Finally, we call the attention to the fact that the 3-3-1 model with right-handed neutrinos accommodate naturally the inverse seesaw mechanism.
