| 摘 要： | 本文应用SU(N)×S与SO(2N)×S作为大统一规范群,对代大统一模型的各种方案进行了全面分析。我们的结论是:SU(7)×S,SU(8)×S,SO(14)×S和SO(16)×S是比较好的代大统一规范群。本文给出了SO(14)×S与SO(16)×S两个代大统一模型。它们容纳了四代通常费米子,并保持SU(3)c渐近自由性质。模趔保留了SO(10)模型中得到的全部好的结果,克服了标准大统一模型中“代“的困难。

SU(N) AND SO(2N) GRAND UNIFIED MODELS |
| |
| Abstract: | Using SU(N) and SO(2N) Grand Unified gange groups, a systematic analysis of all possille flavour GUT models based on the low rank group SU(N)×S and SO(2N)×S is presented. It is found that SU(7)×S, SU(8)×S, SO(14)×S and SO(16)×S are the satisfactory gauge groups of flavour grand unification. In addition, SO(14)×S与SO(16)×S modeles are discussed in detail. All thcse models can accommodate four gennrations of ordinary fermions and preserve the asympotic freedom of SU(3)c. |
