We carry out lattice simulations of a cosmological electroweak phase transition for a Higgs mass m h similar or equal to 126GeV. The analysis is based on a dimensionally reduced effective theory for an MSSM-like scenario including a relatively light coloured SU(2)-singlet scalar, referred to as a right-handed stop. The non-perturbative transition is stronger than in 2-loop perturbation theory, and may offer a window for electroweak baryogenesis. The main remaining uncertainties concern the physical value of the right-handed stop mass which according to our analysis could be as high as m tn R similar or equal to 155GeV; a more precise effective theory derivation and vacuum renormalization than available at present are needed for confirming this value.
