Abstract

We report results of a study of the end point of the electroweak phase transition of the SU(2) gauge-Higgs model defined on a four-dimensional isotropic lattice with Nt = 2. Finite-size scaling study of Lee-Yang zeros yields λc = 0.00116(16) for the end point. Combined with a zero-temperature measurement of Higgs and W boson masses, this leads to MH,c = 68.2 ± 6.6 GeV for the critical Higgs boson mass. An independent analysis of Binder cumulant gives a consistent value λc = 0.00102(3) for the end point.
