Abstract

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 Nt=2. A finite-size scaling study of Lee-Yang zeros yields the value of the Higgs self-coupling of the end point at λc=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 W boson masses, this leads to MH,c=73.3±6.4 GeV for the critical Higgs boson mass beyond which the electroweak transition turns into a crossover.
