Computation of β(gc) at O(1/N2) in the O(N) Gross Neveu Model in Arbitrary Dimensions
Abstract
By using the corrections to the asymptotic scaling forms of the fields of the O(N) Gross Neveu model to solve the dressed skeleton Schwinger Dyson equations, we deduce the critical exponent corresponding to the β-function of the model at O(1/N2).
