Fourth Generation -- Towards Effect of Large Yukawa Coupling

Abstract

In this talk we cover two threads regarding the 4th generation: on CP violation, from Earth up to the Heavens, i.e. from accelerator-based experimental studies, towards baryon asymmetry of the Universe; and on direct search bounds on $m_{t'}$ and $m_{b'}$, towards the possibility of electroweak symmetry breaking through large Yukawa couplings. Prospects and discussions are presented.Comment: Plenary talk presented at TOP2010, May 31 - June 4, 2010, Bruges, Belgiu
