Abstract

We study the electroweak phase transition and the critical bubble in the\nscale-invariant two Higgs doublet model taking the recent LHC data into\naccount. The sphaleron energy in this model is evaluated for the first time. It\nis found that the strong first-order electroweak phase transition is the\ninevitable consequence to be consistent with the observed 125 GeV Higgs boson.\nIn such a case, the signal strength of the Higgs decay to two gammas and the\ntriple Higgs boson coupling could deviate from the SM values by -10% and\n+82%, respectively.\n
