论文摘要
在这项工作中，我们专注于Carroll-Field-Jackiw（CFJ）修饰的电动力学，并结合CPT-eve-eve-ever-ever-e lorentz侵入贡献。我们在拉格朗日的密度中添加了光子质量术语，并研究了该贡献是否可以使理论统一的问题。该分析基于修饰光子传播器的极点结构以及光学定理的有效性。实际上，我们发现大规模的CFJ型修饰在树级时是统一的。该结果为光子质量如何减轻恶性行为提供了进一步的例子。
In this work we focus on the Carroll-Field-Jackiw (CFJ) modified electrodynamics in combination with a CPT-even Lorentz-violating contribution. We add a photon mass term to the Lagrange density and study the question whether this contribution can render the theory unitary. The analysis is based on the pole structure of the modified photon propagator as well as the validity of the optical theorem. We find, indeed, that the massive CFJ-type modification is unitary at tree-level. This result provides a further example for how a photon mass can mitigate malign behaviors.
