摘要：

The finite-temperature symmetry restoration in the four-dimensional θ4 theory with four components and with an infinite self-coupling is studied by means of Monte Carlo simulations on lattices with time extensions Lt = 4,5,6 and space extensions 123-283. The numerical calculations are done by means of the Wolff cluster algorithm which is very efficient for simulations near a phase transition. The numerical results are in goof agreement with an improved one-loop expansion and with the 1/N-expansion, indicating that in the electroweak theory the symmetry restoration temperature Tsr is about 350 GeV. © 1990.
