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

Abstract

The electroweak phase transition is considered in framework of the reduced minimal 3-3-1 model (RM331). Structure of phase transition in this model is divided into two periods. The first period is the phase transition SU(3) ---> SU(2) at TeV scale and the second one is SU(2)--> U(1), which is the like-Standard Model electroweak phase transition. When mass of the neutral Higgs boson (h_1) is taken to be equal to the LHC value: m_{h_1}=125 GeV, then these phase transitions are the first order phase transitions, the mass of Z_2 is about 4.8 TeV; and we find the region of parameter space with the first order phase transition at v_{\rho_0}=246 GeV scale, leading to an effective potential, where mass of the charged Higgs boson is in range of 4.154 TeV < m_{h_{++}} < 5.946 TeV. Therefore, with this approach, new bosons are the triggers of the first order electroweak phase transition with significant implications for the viability of electroweak baryogenesis scenarios.Comment: 21 pages, 3 figure

Electroweak phase transition in the economical 3-3-1 model

“…In a previous work [37], we have considered the EWPT in the reduced minimal 3-3-1 (RM331) model due to its simplicity, and found that our approach can be applied to the more complicated 3-3-1 models. In the present work, we follow the same approach for the economical 3-3-1 (E331) model [38][39][40][41][42][43][44], whose lepton sector is more complicated than that of the RM331 model.…”

Early Universe in the SU(3)_L?(1)_X Electroweak Models

“…This phase transition involves exotic quarks, heavy bosons, without involvement of the SM particles, so υ ρ is omitted in this phase transition. The effective potential can be rewritten as follows (Phong et al, 2013):…”

Baryogenesis in the Zee-Babu model with arbitrary ξ gauge

“…[2,4,5] as well as its various extended versions [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. For the SM, although the EWPT strength is larger than unity at the electroweak scale, the mass of the Higgs boson must be less than 125 GeV [2,4,5]; so the EWBG requires new physics beyond the SM at the weak scale [6].…”

“…Many extensions such as the two-Higgs-doublet model, the reduced minimal 3-3-1 model, the economical 3-3-1 model, or the minimal supersymmetric standard model, have a strongly first-order EWPT and the new sources of CP violation, which are necessary to account for the BAU; triggers for the first-order EWPT in these models are heavy bosons or dark matter candidates [7][8][9][10][11][16][17][18]20]. However, most research of the EWPT are the Landau gauge.…”
