Abstract
We present results from numerical studies of the finite temperature phase transition of the (3+1)d O(N)-symmetric non-linear sigma model for N = 1,2 and 3. We study the dependence of the width of the 3d critical region on N and we show that the broken phase scaling region is much wider for N = 2 and 3 than for N = 1. We also compare the widths of the critical region in the low T and high T phases of the O(2) model and we show that the scaling...
