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

摘要： 在本文中，我们回顾了一些在不包含奇异轻子的3-3-1规范模型框架下提供轻子中微子的机制。 关于最小的3-3-1模型，我们注意到该模型的微扰范围直到5 TeV。 这需要替代机制来生成轻子中微子。 在本综述中，我们讨论了两种能够在最小3-3-1模型框架下生成轻子中微子的机制。 关于包含右旋中微子的3-3-1模型，我们注意到其中生成轻左旋中微子的机制也会生成轻右旋中微子。 最后，我们注意到包含右旋中微子的3-3-1模型自然地容纳了逆向跷跷板机制。 显示英文摘要

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.
