Abstract
The classical transitions between topologically distinct vacua in a SU(2)–Higgs model, using a Higgs field of mass approximately 120 GeV , is examined to probe the crossover region between the symmetric and broken phase. Assuming the Higgs mass is constant, we find the width of this crossover region is approximately 20% of the average temperature. We suggest that this observable is a better parameter to explore this region of phase space than equal-time correlation functions.
