$\epsilon$-Expansion in the Gross-Neveu Model from Conformal Field Theory

Abstract

We compute the anomalous dimensions of a class of operators of the form $(\bar{\psi }\psi {)}^p$ and $(\bar{\psi }\psi {)}^p\psi$ to leading order in $\epsilon$ in the Gross-Neveu model in $2+\epsilon$ dimensions. We use the techniques developed in arXiv: 1505.00963.
