【摘要】 本文讨论了以SU(N)作大统一群的大统一前子模型,并列出了所有SU(N)群的所有反常相消和渐近自由的表示,给出了SU(N)大统一前子模型的一些可能的前子内容,并详细讨论了表示为(N—4)+日的SU(N)大统一前子模型,得到了g_N=(N—5)代夸克和轻子。更多还原

【Abstract】 In this paper, taking SU(N) as the grand unifed group, we discuss the grand unified preon model, and give all anomaly—free and asymptotically free nepresentations of all SU(N) and some possible preon representations in SU(N) grand unified preon model. We also discuss SU(N) grand unified preon model with preon representation (N—4)+日in detail and get g_N=N—5 generations of quarks and leptons.更多还原
