三Higgs双重态模型中的轻子质量与混合

Lepton masses and mixing in a three-Higgs doublet model

Joris Vergeest, Marek Zrałek, Bartosz Dziewit, Piotr Chaber

AI总结:

在三Higgs双重态模型框架下,研究阶数小于1035的离散非阿贝尔群对轻子质量与混合角的预测能力,发现无群能完全预测轻子数据,但$Δ(96)$和$S_4$分别能部分解释中微子和Dirac中微子的混合实验数据。

摘要:

在三Higgs双重态模型(3HDM)框架下,我们寻找能给出轻子质量及其混合角之间关系的离散味对称性。我们探索了阶数小于1035的离散非阿贝尔群,将中微子视为Majorana或Dirac粒子。尽管模型中存在自由动力学参数,但没有一个群能完全预测轻子数据。然而,部分被扫描的群能提供正确的轻子数据,要么给出正确的轻子数据,要么给出正确的带电轻子质量。$Δ(96)$是与中微子质量和PMNS混合实验数据相容的最小群。$S_4$是Dirac中微子混合的近似对称性,其参数与测得的$θ_{12}$、$θ_{23}$、$θ_{13}$相差约$3σ$。

英文摘要:

In the three-Higgs doublet model (3HDM) frame, we search for discrete flavour symmetries that give relations among the lepton masses and their mixing angles. We explore discreet non-Abelian groups of order less than 1035, treating neutrinos as Majorana or Dirac particles. Despite the free dynamic parameters available in the model, none of the groups fully predicts the lepton data. However, some of the scanned groups provide either the correct neutrino masses and mixing angles or the correct masses of the charged leptons. $Δ(96)$ is the smallest group compatible with the experimental data of neutrino masses and PMNS mixing. $S_4$ is an approximate symmetry of Dirac neutrino mixing, with parameters staying about $3σ$ apart from the measured $θ_{12}$, $θ_{23}$, $θ_{13}$.
