Abstract
We compare the shape of the constraint effective potential as obtained from numerical simulations in the scaling limit of the non-linear σ-model in d=3 and d=4 to recent results from chiral perturbation theory. Whereas in d=4 already the lowest order chiral perturbation theory turns out to describe the data well, we had to use the next to leading order in d=3 to find satisfactory agreement.
