Baryon Asymmetry: Evidence of CP Violation and Phase Transition in the Early Universe ?

Abstract

A talk was given on the baryon asymmetry of our universe within the electroweak energy scale which was the theme for the 23rd INS Symposium. It was intended for non-experts by a non-expert speaker. A model is analized explicitly in which the lepton number produced from the bubble walls is converted afterwards to the baryon asymmetry.Phase transition dynamics is simulated, including the temporal develpment and the fusion effect of the nucleated bubbles.
