摘要：

By performing a critical point renormalization of the 3-vertex of the O(N) Gross-Neveu model at O(1/N2) in the large N expansion, we determine the critical exponent corresponding to the anomalous dimension of the vertex in arbitrary dimensions, and subsequently deduce the anomalous dimension of the auxiliary field, sigma, and the mass to the same order.
