论文摘要
在许多BSM理论中，尤其是胆量中，引入了BROUT-ENGLERT-HIGGS效果，可以多种破坏对称性的破坏模式。选择特定模式的可能性通常对于理论的现象学生存能力是决定性的。除了扰动理论之外，有必要通过明显的规范描述来代替Brout-Englert-Higgs效应。我们研究了最简单的情况，具有多种破碎模式，一个$ \ textrm {su}（3）$ yang-mills理论与晶格上的伴随表示中的单个标量“ higgs”字段相连。我们发现，只有一种模式保留在固定参数和固定策略处，并且相关的量子有效电位来自许多方面的非平凡相互作用。
In many BSM theories, especially GUTs, introducing a Brout-Englert-Higgs effect allows for multiple breaking patterns of the gauge symmetry. The possibility to select a particular pattern is usually decisive for the phenomenological viability of a theory. Beyond perturbation theory it is necessary to replace the Brout-Englert-Higgs effect by a manifestly gauge-invariant description. We study the simplest case with multiple breaking patterns, an $\textrm{SU}(3)$ Yang-Mills theory coupled to a single scalar `Higgs' field in the adjoint representation, on the lattice. We find that only one pattern remains at fixed parameters and gauge-fixing strategy, and that the associated quantum effective potential emerges from a non-trivial interplay of many aspects.
