分立对称性与三代费米子的统一(Ⅰ)

DISCRETE SYMMETRY AND UNIFICATION OF THREE GENERATIONS OF ORDINARY FERMLONS

本文提出了一个SU(7)规范群的代大统一模型。它可容纳三代具有V—A型弱作用的通常费米子,实现了现实费米子的统一描述。模型保留了SU(5)大统一模型的部全好的结果,同时给出了夸克轻子间一些质量关系式及第一Cabibbo角。

In the artic le a SU (7) flavor grand unified model accommodating tbree gnerations of ordinary fermions with V-A weak interaction is proposed and a unified discription of realistic fermions is realized in this model It retains all the good results of the SU (5) GUT, and gives some desired mass relations betweem quarks and leptons as well as the first Cabibbo angle.
