在具有强 4-费米相互作用的单代费米子的 E_6 GUT 模型中研究了动态对称性破缺。借助米歇尔猜想对有效势进行了分析分析，并对结果进行了数值验证。我们发现 E_6 对称性自发破缺到 F_4 或 Sp(8) 或 G_2 或 SU(3)，具体取决于 27/351 通道中的 4-费米耦合常数 G_27 和 G_351 中哪一个更强。还讨论了获得其他类型的破坏模式的可能性。
Dynamical symmetry breaking is studied in an E_6 GUT model of a single generation of fermions with strong 4-fermi interactions. The effective potential is analyzed analytically by the help of Michel's conjecture and the result is confirmed numerically. We find that the E_6 symmetry is spontaneously broken either to F_4 or to Sp(8) or G_2 or SU(3), depending on which of the 4-fermi coupling constants G_27 and G_351 in the 27/351 channels is stronger. The possibilities for obtaining other type of breaking patterns are also discussed.
