Lorentz破坏QED中的规范反常

Gauge anomalies in Lorentz-violating QED

Tiago R. S. Santos, Rodrigo F. Sobreiro

摘要:

本文研究了洛伦兹破坏QED中的规范反常问题。为此,我们选择在代数重整化方法中使用Becchi-Rouet-Stora-Typhoon形式主义,将我们的研究减少到上同调问题。由于这种方法是独立的重整化方案,这里得到的结果是一般的。我们发现,在微扰理论中,Lorentz破坏的QED在所有的阶数下都是不存在规范反常的。

英文摘要:

In this work we study the issue of gauge anomalies in Lorentz-violating QED. To do so, we opt to use the Becchi-Rouet-Stora-Tyutin formalism within the algebraic renormalization approach, reducing our study to a cohomology problem. Since this approach is independent of the renormalization scheme, the results obtained here are expected to be general. We find that the Lorentz-violating QED is free of gauge anomalies to all orders in perturbation theory.
