摘要

我们将最近提出的非常狭义相对论模型的 Sim(2) 不变红外正则化扩展到了γ5 迪拉克矩阵。然后，我们求解了非常狭义相对论施文格模型，发现了手性反常，并阐明了它在新背景下的意义。此外，我们还证明了四维时空中的三角异常与标准量子电动力学中的同一对象是一致的。最后，我们应用红外正则化计算了非常狭义相对论格罗斯-涅维模型的大 N 极限。

Infrared Regularization of Very Special Relativity Models

We extend the Sim(2) invariant infrared regularization of Very Special Relativity models, that we have proposed recently, to include γ5 Dirac matrix. Then, we solve the Very Special Relativity Schwinger model, find the chiral anomaly, and clarify its meaning in the new context. In addition, we show that the triangle anomaly in four space-time dimensions agrees with the same object in standard quantum electrodynamics. Finally, we apply the infrared regularization to compute the large N limit of the Very Special Relativity Gross–Neveu model.
