摘要:

我们建立了第一个3-3-1模型的基础上$Δ(27)$离散群对称性,符合费米子质量和混合。在所考虑的模型中,中微子的质量是由I型和II型跷跷板机制的组合介导的三个重右手Majorana中微子和三个$SU(3)_{L}$标量反extets,分别产生。进一步,从轻子混合角与实验值的一致性出发,得到了$-\frac{π}{2}$的非零轻子Dirac CP破坏相位.我们的模型具有有效的马约拉纳中微子质量参数的中微子双β衰变,与值$m_{ββ}=$ 10和18毫电子伏特的正常和倒置的中微子质量层次,分别。

英文摘要:

We build the first 3-3-1 model based on the $Δ(27)$ discrete group symmetry, consistent with fermion masses and mixings. In the model under consideration, the neutrino masses are generated from a combination of type-I and type-II seesaw mechanisms mediated by three heavy right-handed Majorana neutrinos and three $SU(3)_{L}$ scalar antisextets, respectively. Furthermore, from the consistency of the leptonic mixing angles with their experimental values, we obtain a non-vanishing leptonic Dirac CP violating phase of $-\frac{π}{2}$. Our model features an effective Majorana neutrino mass parameter of neutrinoless double beta decay, with values $m_{ββ}=$ 10 and 18 meV for the normal and the inverted neutrino mass hierarchies, respectively.
