Abstract
Our analysis shows that SM-like electroweak phase transition (EWPT) in the (2-2-1) model is a first-order phase transition at the GeV scale (the SM scale). Its strength () is about and the masses of new gauge bosons are larger than TeV when the second VEV is larger than GeV in a three-stage EWPT scenario and the coupling constant of 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.
