| 摘 要： | 本文提出了SU(3)×SO(5)手征三前子复合模型,应用′t Hooft反常机制条件得到了三代普通夸克和轻子,而且无例外粒子。模型中规范色—味子群SU(3)_C×SU(2)_L×U(1)_Y在前子层次具有渐近自由性质,同时整体手征对称群SU(15)×SU(3)不破缺,因此现实中有兴趣的物理标度∧_(CF)<∧_(MC)《∧_(GUT)是可能存在的。

| Abstract: | In this paper, a SU(3)×SO(5) chiral three—preen composite model is proposed. By applying the ′t Hooft anomaly matching condition an unique solution has been obtained that gives rise to three generatins of ordinary quarks and leptons without exotic fermions. In this model, the gauged color—flaver subgroup SU(3)×SU(2)_L×U(1)_Y is asymptotically free at the preon level and the global chiral symmetry SU(15)×SU(3) remains unbroken, therefore it might exist that a realistic physical scale ∧_(CF)<∧_(MC)《∧_(GUT). |
