Dear All members,

 We are pleased to announce a Journal club by SangHui Im and Seokhoon Yun.

 

* Title: Baryogenesis in a CP invariant theory, Overview of COSMO-15

* Speaker: Seokhoon Yun, SangHui Im (CTPU) (at KAIST Munji Campus)

 

* Date: 12:00-1:00 PM, 25 Sep 2015

 * Abstract: We consider baryogenesis in a model which has a CP invariant Lagrangian, CP invariant initial conditions and does not spontaneously break CP at any of the minima. We utilize the fact that tunneling processes between CP invariant minima can break CP to implement baryogenesis. CP invariance requires the presence of two tunneling processes with opposite CP breaking phases and equal probability of occurring. In order for the entire visible universe to see the same CP violating phase, we consider a model where the field doing the tunneling is the inflaton. (Seokhoon Yun)

I will give an overview of COSMO-15 and introduce some personally interesting issues. (SangHui Im)
