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. | MINISTRY OF EDUCATION VIETNAM ACADEMY AND TRAINING OF SCIENCE AND TECHNOLOGY GRADUATE UNIVERSITY OF SCIENCE AND TECHNOLOGY NGUYEN CHI THAO THE ELECTROWEAK PHASE TRANSITION IN THE ZEE-BABU AND SU 3 C SU 3 L U 1 X U 1 N GAUGE MODELS Major Theoretical and Mathematical Physics Code 9 44 01 03 SUMMARY OF PHYSICS DOCTORAL THESIS HA NOI- 2019 The thesis is completed at GRADUATE UNIVERSITY OF SCI- ENCE AND TECHNOLOGY VIETNAM ACADEMY OF SCIENCE AND TECHNOLOGY.

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 A.Sakharov 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
