无歧义的四维Lorentz破缺Chern-Simons action

The ambiguity-free four-dimensional Lorentz-breaking Chern-Simons action

F. A. Brito, J. R. Nascimento, E. Passos, A. Yu. Petrov

摘要:

通过规范场与旋量场的适当的Lorentz破缺耦合,产生了四维Lorentz破缺有限定Chern-Simons类作用量.与已知的计算方案不同,在该方案中,发现该项是正则化独立的。

英文摘要:

The four dimensional Lorentz-breaking finite and determined Chern-Simons like action is generated as a one loop perturbative correction via an appropriate Lorentz-breaking coupling of the gauge field with the spinor field. Unlike the known schemes of calculations, within this scheme this term is found to be regularization independent.
