Is there a hot electroweak phase transition at m$_{H}$ $\geq$ m$_{W}$?

We provide non-perturbative evidence for the fact that there is no hot electroweak phase transition at large Higgs masses, m_H = 95, 120 and 180 GeV. This means that the line of first order phase transitions separating the symmetric and broken phases at small m_H has an end point m_{H,c}. In the minimal standard electroweak theory 70 GeV <m_{H c}< 95 GeV and most likely m_{H,c} \approx 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.
