摘要：

For OMICRON(NU)-symmetric spin models in the spontaneously broken phase, we study the distribution of the mean field PHI = V -1 integral-d/d-chi-phi(chi) at large volume. We us results from chiral perturbation theory to show that this distribution obeys a scaling law. The shape of the constraint effective potential is determined in the scaling limit.
