摘要：

We present new data for O(4) and O(8) σ-models generated in cluster simulations at large correlation length. Together with results for O(3) they are analyzed with the conclusion that asymptotic scaling sets in earlier with growing n. There is good agreement with recently proposed exact results for m ΛMS, in particular when a resummation technique is used and 3-loop terms are included in the data analysis. © 1990.
