   Recent BELLE results on CP violation in Bd --> Phi Ks
 
 
 
   
Abstract


The CP violation in decay modes with b->s Penguin transition is quite interesting because it is sensitive to a new particle with new phase in the loop which gives the deviation in size of the CP violation from that of B ->J/psi Ks decay.
The present Belle results on such decay modes are reported.  In particular, B -> phi Ks is theoretically clean and the result indicates a hint of deviation though more data are needed to confirm.
