我们讨论了$\mathcal{P}\mathcal{T}$-对称阿贝尔规范场理论以及它们对产生矢量玻色子质量的Englert-Brout-Higgs机制的扩展。规范不变性是不简单的,我们讨论了不同的相关问题,以及解决方案,其中包括耦合规范场的电流是不保守的。非厄米性必然排除了洛伦兹规范条件,但仍然允许理论的一致表述。因此,我们将Englert-Brout-Higgs机制推广到$\mathcal{P}\mathcal{T}$-对称场论,为构建标准模型的非厄米扩展和粒子模型构建的新场景开辟了道路。
We discuss $\mathcal{P}\mathcal{T}$-symmetric Abelian gauge field theories as well as their extension to the Englert-Brout-Higgs mechanism for generating a mass for a vector boson. Gauge invariance is not straightforward, and we discuss the different related problems as well as a solution which consists in coupling the gauge field to a current that is not conserved. Non-Hermiticity then necessarily precludes the Lorenz gauge condition but nevertheless allows for a consistent formulation of the theory. We therefore generalize the Englert-Brout-Higgs mechanism to $\mathcal{P}\mathcal{T}$-symmetric field theories, opening the way to constructing non-Hermitian extensions of the Standard Model and new scenarios for particle model building.
