Abstract

We use the recently developed CFT techniques of Rychkov and Tan to compute anomalous dimensions in the O(N) Gross-Neveu model in d = 2 + epsilon dimensions. To do this, we extend the \textbackslashcowpie contraction'' algorithm of arXiv:1506.06616 to theories with fermions. Our results match perfectly with Feynman diagram computations.
