Direct CP violation of $b \rightarrow s\gamma$ and CP asymmetries of non-leptonic B decays in squark flavor mixing

Abstract

We study the contribution of the squark flavor mixing from the $LR(RL)$ component of the squark mass matrices to the direct CP violation of the $b\to s\gamma$ decay and the CP-violating asymmetry in the non-leptonic decays of $B$ mesons. The magnitude of the $LR(RL)$ component is constrained by the branching ratio and the direct CP violation of $b\to s\gamma$. We predict the correlation of the CP asymmetries among $A_{\text{CP}}^{b \to s \gamma}$, $\mathcal{S}_{\phi K_S}$ and $\mathcal{S}_{\eta 'K^0}$ of the B decays. The precise data of these CP violations will give us the crucial test for our framework of the squark flavor mixing.
