最近的研究表明，在四维nambu - jona - lasinio （NJL）型模型中，对称分解为其特殊子群并不特殊，而是比分解为规则子群更常见，其中费米子属于复杂的表示。我们对属于不可约旋量表示的各种带费米子的theNJL模型进行了相同的分析。我们发现对称性破缺成特殊或规则的子群与费米子表示的类型有一定的关系；即复杂的、真实的、伪真实的表征。
It was recently shown that in four-dimensionalNambu–Jona-Lasinio (NJL) type models, thesymmetry breaking into its special subgroups is not special but much more common than that into the regular subgroups, where the fermions belong to complex representations of. We perform the same analysis for theNJL model for variouswith fermions belonging to an irreducible spinor representation of. We find that the symmetry breaking into special or regular subgroups has some correlation with the type of fermion representations; i.e. complex, real, pseudo-real representations.
