The Minimal Chiral Schwinger model with the minimal Wess-Zumino action

We examine the recently proposed minimal chiral Schwinger model with the new Wess-Zumino action. From the physical requirement, we restrict the regularization ambiguity and show that it is equivalent to the Schwinger model.

Dynamical behavior in the (2+1)-dimensional Gross-Neveu model with a Thirring interaction.

We analyze (2+1)-dimensional Gross-Neveu model with a Thirring interaction, where a vector-vector type four-fermi interaction is on equal terms with a scalar-scalar type one. The Dyson-Schwinger equation for fermion self-energy function is constructed up to next-to-leading order in 1/N expansion. We determine the critical surface which is the boundary between a broken phase and an unbroken one in (
