εε-Expansion in the Gross-Neveu Model from Conformal Field Theory

preprint2016arXivOpen access

Abstract

We compute the anomalous dimensions of a class of operators of the form (ψˉψ)p(\barψψ)^p and (ψˉψ)pψ(\barψψ)^pψ to leading order in εε in the Gross-Neveu model in 2+ε2+ε dimensions. We use the techniques developed in arXiv: 1505.00963.
