Abstract
We use the background field method to systematically derive CFT data for the critical vector model in three dimensions, and the Gross-Neveu model in dimensions . Specifically, we calculate the OPE coefficients and anomalous dimensions of various operators, up to next-to-leading order in the expansion.
