具有最大大气角的夸克和轻子的S4模型

An S4 model for quarks and leptons with maximal atmospheric angle

S. Morisi, E. Peinado

摘要:

我们考虑一个模型的夸克和轻子质量和混合的基础上S4味对称性。该模型包含六个希格斯二重态,其中三个给予轻子质量,另外三个给予夸克质量。带电费米子和夸克质量产生于可重整化相互作用,而中微子马约拉纳质量则通过有效的五维温伯格算符产生。从标量势的最小化的研究中,我们发现了一个剩余的μ-τ对称性的中微子部门预测零反应堆的角度和最大的大气角度和夸克部门,我们发现了一个四零纹理。我们给出了夸克扇区的质量等级和混合角的拟合。

英文摘要:

We consider a model for quark and lepton masses and mixings based on S4 flavor symmetry. The model contains six Higgs doublets where three of them give mass to the leptons and the other three gives mass to the quarks. Charged fermion and quark masses arise from renormalizable interactions while neutrino Majorana masses are generated through effective dimension five Weinberg operator. From the study of the minimization of the scalar potential we found a residual mu-tau symmetry in the neutrino sector predicting zero reactor angle and maximal atmospheric angle and for the quark sector we found a four-zero texture. We give a fit of the mass hierarchies and mixing angles in the quark sector.
