关于夸克和轻子族的起源--对四个族的预言

On the origin of families of quarks and leptons - predictions for four families

G. Bregar, M. Breskvar, D. Lukman, N. S. Mankoc Borstnik

摘要:

统一所有内部自由度的方法--由我们中的一个人提出--提供了一种理解夸克和轻子族的新方法:初始拉格朗日密度的一部分,单位为d(=1+13),它包括两种自旋联系场--两种Clifford代数对象的规范场--将右旋夸克和轻子变换为左旋夸克和轻子,表现为d=1+ 3标准模型的汤川联轴器。我们研究了对称性破缺的方式对汤川耦合的影响,并估计了第四族夸克质量和混合矩阵的性质,研究了第四族夸克和轻子在新一代加速器上以足够低的能量出现的可能性。

英文摘要:

The approach unifying all the internal degrees of freedom--proposed by one of us--is offering a new way of understanding families of quarks and leptons: A part of the starting Lagrange density in d(=1+13), which includes two kinds of spin connection fields--the gauge fields of two types of Clifford algebra objects--transforms the right handed quarks and leptons into the left handed ones manifesting in d=1+3 the Yukawa couplings of the Standard model. We study the influence of the way of breaking symmetries on the Yukawa couplings and estimate properties of the fourth family--the quark masses and the mixing matrix, investigating the possibility that the fourth family of quarks and leptons appears at low enough energies to be observable with the new generation of accelerators.
