Lorentz破坏下的大质量Yang-Mills理论的规范场谱

Gauge field spectrum in massive Yang-Mills theory with Lorentz violation

T. R. S. Santos, R. F. Sobreiro, A. A. Tomaz

摘要:

在树水平上计算了具有Lorentz破坏的有质量CPT-奇杨-米尔斯传播子的谱。这种修正是由于Lorentz破坏的杨-Mills理论的乘法重整化的迫切性所产生的质量项。因果关系分析进行从组和前速度,类空和类时背景张量。它表明,通过要求因果关系,它总是可以定义一个物理扇区的规范传播子。因此,如果考虑到Faddeev-Popov鬼,预计该模型也是酉的。

英文摘要:

The spectrum of the massive CPT-odd Yang-Mills propagator with Lorentz violation is performed at tree-level. The modification is due to mass terms generated by the exigence of multiplicative renormalizability of Yang-Mills theory with Lorentz violation. The causality analysis is performed from group and front velocities for both, spacelike and timelike background tensors. It is show that, by demanding causality, it is always possible to define a physical sector for the gauge propagator. Hence, it is expected that the model is also unitary, if one takes the Faddeev-Popov ghost into account.
