Abstract
We use the recently developed CFT techniques of Rychkov and Tan to compute anomalous dimensions in the Gross-Neveu model in dimensions. To do this, we extend the "cowpie contraction" algorithm of arXiv:1506.06616 to theories with fermions. Our results match perfectly with Feynman diagram computations.

v2: a correction in contraction algorithm (main results unchanged), references and an appendix added, discussion less rushed
