The imperative of the thesis In physics baryon asymmetry is also known as material asym- metry. This issue is currently an interesting problem. Today to ex- plain baryon asymmetry scientists use two mechanisms Leptongene- sis and Baryogenesis. A model having Baryogenesis must be satisfied the three conditions of 2 . The standard model SM has been successful in explaining experimental results 4 . Source of CP violation in SM is smaller Baryon asymmetry of Universe BAU and there is no strong phase- one transition with the Higgs mass mH 125 GeV. In other words SM is not enough mH 125 GeV the first order phase transition 6-8 . 2. Research targets of the thesis We want to analyze the baryon asymmetry problem and de- termine the contribution role of newl particles in some extended stan- dard models. We have done the thesis The electroweak phase transition in the Zee-Babu and SU 3 C SU 3 L U 1 U 1 N gauge models 3. The main research contents of the thesis In addition to the introduction and conclusion of the thesis there are three
