Lattice results show no standard model ISM) electroweak phase transition (EWPT) for Higgs masses approximate to 72 GeV. which is below the present experimental limit. perturbation theory and 3-dimensional simulations indicate an EWPT in the minimal supersymmetric SM (MSSM) that is strong enough fur baryogenesis up to m(h) approximate to 105 GeV. In this Letter we present the results of our large scale 4-dimensional MSSM EWPT simulations. We carried out infinite volume and continuum limits and found a transition whose strength agrees well with perturbation theory, allowing MSSM electroweak baryogenesis at least up to m(h) = 103 +/- 4 GeV. We determined the properties of the bubble wall.
