New Source of CP violation in B physics ?

Abstract

In this talk we discuss how the down type left-right squark mixing in Supersymmetry can induce a new source of CP violation in the time dependent asymmtries in B --> phi K process. We use QCD improved factorization process to calculate the hadronic matrix element for the process and find the allowed parameter space for $\rho$ and $\varphi$, the magnitude and phase of the down type LR(RL) squark mixing parameter ${\delta }_{LR(RL)}^{bs}$. In the same allowed regin we calculate the expected CP asymmtries in the $B\to \varphi K^{\ast }$ process.
