Popis: | We provide non-perturbative evidence for the fact that there is no hot electroweak phase transition at large Higgs masses, mH = 95, 120 and 180 GeV. This means that the line of first order phase transitions separating the symmetric and broken phases at small mH has an end point mH,c. In the minimal standard electroweak theory 70 GeV < mH,c < 95 GeV and most likely mH,c ≈ 80 GeV. If the electroweak theory is weakly coupled and the Higgs boson is found to be heavier than the critical value (which depends on the theory in question), cosmological remnants from the electroweak epoch are improbable. |
