We calculate the β-function for the Gross-Neveu model up to three loop order. The result found is β(λ)=(N-1) [-4λ2/4π+8λ3/(4π) 2-276λ4/(4π)3] showing an unexpected lack of a term proportional to N2 in the last term. This suggests the existence of an N-independent rescaling of the coupling that eliminates all but the first two terms of the β-function. |
