Abstract: (Elsevier)

There are indications that, as a consequence of the trivality of the scalar φ 4 theory, the Weinberg-Salam model is massive free field theory. However, considering theWS model as an effective field theory, an upper bound for the Higgs mass can exist. We have studied this phenomenon by simulating the SU(2) gauge Higgs model on a lattice. The results indicate that R max = m H / m W | max = 9.3 ± 1. However, serious finite size effects make it unfeasible to explore the region m H ⩽ Λ cutoff with Monte Carlo simulation.
