Abstract
We calculate CFT data for the Gross-Neveu model in dimensions at the next-to-leading order in the expansion. In particular, we make use of the background field method to derive various conformal triangles involving the composite operator , for the Hubbard-Stratonovich field . We then apply these conformal triangles to obtain the corresponding OPE coefficients.
