Electroweak phase transition in the reduced minimal 3-3-1 model

Vo Quoc Phong, Vo Thanh Van, Hoang Ngoc Long

The electroweak phase transition is considered in the framework of the reduced minimal 3-3-1 model. The structure of the phase transition in this model is divided into two parts. The first part is the phase transition SUð3Þ ! SUð2Þ at the TeV scale, and the second is SUð2Þ ! Uð1Þ, which is like the standard model electroweak phase transition. When the mass of the neutral Higgs boson (h1) is taken to be equal to the LHC value, mh1 ¼ 125 GeV, these phase transitions are first-order transitions; the mass of Z2 is about 4.8 TeV, and we find the region of parameter space with the first-order phase transition at the v0 ¼ 246 GeV scale, leading to an effective potential where the mass of the charged Higgs boson is in the range 3:258 TeV
