| ABSTRACT: |
In this talk, feasibility of electroweak baryogenesis in the U(1)-prime extended MSSM (UMSSM) is examined in light of the recently observed 126 GeV Higgs boson. I will begin with a pedagogical review of electroweak baryogenesis. Then I will discuss a baryon number preservation criterion focusing especially on a sphaleron energy, and study strength of the 1st-order electroweak phase transition. Then I will estimate the baryon number density in a specific scenario in which Z'-ino plays an essential role. Finally, I will give a brief summary and outlook. |
