满足互补原理的半单复合模型

本文系统分析了SU(N)×SO(M)半单超色群的手征三前子模型.我们发现:SU(3)×SO(5)模型满足互补原理要求;由′tHooft方程及Bars条件可以给出三代夸克、轻子谱;超色群G_(MC)和规范色味子群G_(CF)都是渐近自由的,因此可以构造出具有低的超色禁闭标度A_(MC)的现实模型.我们还发现,本模型中存在二个超色标度.在这两个标度之间,模型类似于费米——玻色模型,这可以简化前子的动力学.

A COMPOSITE MODEL WITH SEMI—SIMPLE MC GROUP SATISFYING COMPLEMENTARITY

A systematic analysic of the chiral tripreon models with SU(N)×SO(M)metacolor symmetry is made.It isfunded that the SU(3)×SO(5)model satisfies the complementarity and can gave rise to three generations fermionsby tHooft anomaly match condition and Bars condition.In this model metacolor group and color—flavor subgroup areall asymptotically free.So we can give a realistic low scale tripreon model with complementarity.In this model thereare two metacolor energy scales.In the intermediate energgy range between them,the model can behave like afermion—boson constituent model.This may help simplify the preon dynamics.
