标准模型的实A4推广中的夸克-轻子质量关系

Quark-Lepton Mass Relation in a Realistic A4 Extension of the Standard Model

S. F. King, S. Morisi, E. Peinado, J. W. F. Valle

摘要:

我们提出了一个现实的A4扩展的标准模型涉及一个特殊的夸克-轻子质量关系,即第三族质量的比例的第一和第二族质量的几何平均值是相等的向下型夸克和带电轻子。这个关系式近似为重整化群不变量,通常被认为是由Georgi-Jarlskog关系式产生的,但在本模型中没有统一群或超对称性。在中微子部门,我们提出了一个简单的修改,所谓的Zee-Wolfenstein质量矩阵模式,它允许一个可接受的反应堆角度随着大气和太阳的角度从他们的双极大值的偏差。通过数值拟合很好地描述了夸克质量、混合角和CP破坏。

英文摘要:

We propose a realistic A4 extension of the Standard Model involving a particular quark-lepton mass relation, namely that the ratio of the third family mass to the geometric mean of the first and second family masses are equal for down-type quarks and charged leptons. This relation, which is approximately renormalization group invariant, is usually regarded as arising from the Georgi-Jarlskog relations, but in the present model there is no unification group or supersymmetry. In the neutrino sector we propose a simple modification of the so called Zee-Wolfenstein mass matrix pattern which allows an acceptable reactor angle along with a deviation of the atmospheric and solar angles from their bi-maximal values. Quark masses, mixing angles and CP violation are well described by a numerical fit.
