 Abstract: The Renormalization Group flow equations obtained by means of a proper time regulator are used to analyze the restoration of the discrete chiral symmetry at non-zero density and temperature in the Gross–Neveu model in d = 2 + 1 dimensions. The effects of the wave function renormalization of the auxiliary scalar field on the transition have been studied. The analysis is performed for a number of fermion flavors Nf = 12 and the limit of large Nf is also considered. The results are compared with those coming from lattice simulations.
