摘要：

We study the first-order finite-temperature electroweak phase transition of the SU(2) gauge-Higgs model defined on a four-dimensional isotropic lattice with the temporal extension N-t = 2. A finite-size scaling study of Lee-Yang zeros yields the value of the Higgs self-coupling of the end point at lambda(c) = 0.00116(16). An independent analysis of the Binder cumulant gives a consistent value for the end point. Combined with our zero-temperature measurement of Higgs and IV boson masses, this leads to M-H,M-c = 73.3+/-6.4 GeV for the critical Higgs boson mass beyond which the electroweak transition turns into a crossover.
