$ε$-Expansion in the Gross-Neveu CFT
Published 18 Oct 2015 in hep-th | (1510.05287v2)
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 "cowpie contraction" algorithm of arXiv:1506.06616 to theories with fermions. Our results match perfectly with Feynman diagram computations.
