论文摘要
我们为标准模型的任意标量扩展而得出费米仪中的场相关质量。这些质量可用于为各种新物理学的有效潜力构建有效潜力。我们发布了一个灵活的$ \ texttt {Mathematica} $笔记本（$ \ texttt {veffermi} $），该计算执行这些计算并渲染各种模型的大规模现象学研究。在关于量规依赖的重要性的辩论中，我们表明，即使在相对简单的模型中，也存在量规参数中全局最小值不连续的点。这样的观点需要一些注意，表明在检查模型的全局特征时，依赖量规的治疗方法仍然可以给出合理的结果。
We derive the field-dependent masses in Fermi gauges for arbitrary scalar extensions of the Standard Model. These masses can be used to construct the effective potential for various models of new physics. We release a flexible $\texttt{Mathematica}$ notebook ($\texttt{VefFermi}$) which performs these calculations and renders large-scale phenomenological studies of various models possible. Motivated by the debate on the importance of gauge dependence, we show that, even in relatively simple models, there exist points where the global minimum is discontinuous in the gauge parameter. Such points require some care in discovering, indicating that a gauge-dependent treatment might still give reasonable results when examining the global features of a model.
