Abstract

We compute the O(1/N) correction to the stability critical exponent, ω, in the Landau-Ginzburg-Wilson model with O(N) x O(m) symmetry at the stable chiral fixed point and the stable direction at the unstable antichiral fixed point. Several constraints on the O(1/N) coefficients of the four loop perturbative β-functions are computed. © 2002 Elsevier Science B.V. All rights reserved.
