Correction exponents in the Gross–Neveu–Yukawa model at 1/N2

Abstract

We calculate the critical exponents omega +/- in the d-dimensional Gross-Neveu model in 1/N expansion with 1/N-2 accuracy. These exponents are related to the slopes of the ss-functions at the critical point in the Gross-Neveu-Yukawa model. They have been computed recently to four loops accuracy. We checked that our results are in complete agreement with the results of the perturbative calculations.
