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.
