Summary of Physics doctoral thesis: The electroweak phase transition in the Zee-Babu and SU(3)C⊗SU(3)L⊗U(1)⊗U(1)N gauge models

In physics baryon asymmetry is also known as material asymmetry. This issue is currently an interesting problem. Today, to explain baryon asymmetry, scientists use two mechanisms, Leptongenesis and Baryogenesis. A model having Baryogenesis must be satisfied the three conditions of A.Sakharov.

Dynamics of electroweak phase transition in the 3-3-1-1 model

The bubble nucleation in the framework of 3-3-1-1 model is studied. Previous studies show that first order electroweak phase transition occurs in two periods. In this paper we evaluate the bubble nucleation temperature throughout the parameter space. Using the stringent condition for bubble nucleation formation we find that in the first period, symmetry breaking from SU(3) → SU(2), the bubble is formed at the nucleation temperature T = 150 GeV and the lower bound of the scalar mass is 600 GeV.
