摘要

我们重新评估了从类Palatini程序中获得的CPT奇电动力学的替代方案。从更一般的情况出发，我们分析了质量张量中引入的参数的不同值的模型的物理一致性。我们证明，如果局部变换仅在洛伦兹破缺矢量的方向上变化，则模型中存在残余规范不变性。这种残余规范不变性可以扩展到所有模型，这些模型的规范对称性破坏的唯一来源是这样的质量项。

Residual Gauge Invariance in a Massive Lorentz-Violating Extension of QED

We reassess an alternative CPT-odd electrodynamics obtained from a Palatini-like procedure. Starting from a more general situation, we analyze the physical consistency of the model for different values of the parameter introduced in the mass tensor. We show that there is a residual gauge invariance in the model if the local transformation is taken to vary only in the direction of the Lorentz-breaking vector. This residual gauge invariance can be extended to all models whose only source of gauge symmetry breaking is such a mass term.
