$SU(2)$左右对称模型中的Dirac中微子

Dirac neutrinos in a $SU(2)$ left-right symmetric model

Henry Diaz Chavez, V. Pleitez, O. P. Ravinez

摘要:

在一个左右对称模型中,标量扇区由几个双二重态和两个二重态组成,中微子在微扰论中仍然是狄拉克费米子。虽然只有两个双二重态的中微子质量仍然需要微调,但当加入第三个双二重态时,情况就不是这样了。其中一个标量偶极可能是惰性的,因为它受到左右对称性的保护。

英文摘要:

In a left-right symmetric model, with the scalar sector consisting of several bi-doublets and two doublets, neutrinos remain as Dirac fermions in all order in perturbation theory. Although with only two bi-doublets the neutrino masses need still a fine tuning, this is not the case when a third bi-doublet is added. One of the scalar doublet may be of the inert type since it is protected by the left-right symmetry.
