Abstract

Our analysis shows that SM-like electroweak phase transition (EWPT) in the SU(2)1SU(2)2U(1)YSU(2)_1 \otimes SU(2)_2 \otimes U(1)_Y (2-2-1) model is a first-order phase transition at the 200200 GeV scale (the SM scale). Its strength (SS) is about 12.71 - 2.7 and the masses of new gauge bosons are larger than 1.71.7 TeV when the second VEV is larger than 535535 GeV in a three-stage EWPT scenario and the coupling constant of SU(2)2SU(2)_2 group must be larger than 2. Therefore, this first order EWPT can be used to fix VEVs and the coupling constant of the gauge group in electro-weak models.
