标题： Gauge symmetry and radiatively induced terms in dimension-5 non-minimal Lorentz-violating QED

摘要： 在本工作中，我们推导了保证非最小五维洛伦兹破坏QED规范不变性的条件。计算了一环图的二点和三点函数。检查了规范Ward恒等式，并发现保证此非最小框架规范对称性的条件与通常QED的条件相同。还研究了诱导项，并表明费米子部分的非最小洛伦兹破坏$a^{(5)}_F$项可以辐射地诱导光子部分的非最小洛伦兹破坏项。 显示英文摘要

摘要： In this work, we derive the conditions that assure gauge invariance of a non-minimal dimension-5 Lorentz-violating QED. The two and three point functions at one-loop are computed. The gauge Ward identities are checked and the conditions to assure gauge symmetry of this non-minimal framework is found to be the same of the usual QED. Induced terms are also investigated and it is shown that the non-minimal Lorentz-violating $a^{(5)}_F$-term of the fermion sector can induce radiatively a non-minimal Lorentz-violating term in the photon sector.
