Abstract
The CP violation of the neutral B meson is the important phenomenon to search for the new physics. The like-sign dimuon charge asymmetry observed by the DØ Collaboration indicates the CP-violating new physics in the Bs-B¯s mixing. On the other hand, LHCb observed the CP-violating asymmetry in Bs0→J/ψϕ and Bs0→J/ψf0(980), which is consistent with the SM prediction. However, there is still room for new physics of the CP violation. The CKMfitter has presented the allowed region of the new physics parameters taking account of the LHCb data. Based on these results, we discuss the effect of the squark flavor mixing on the CP violation in the Bd and Bs mesons. We predict asymmetries in the non-leptonic decays Bd0→ϕKS, Bd0→η′K0, Bs0→ϕϕ and Bs0→ϕη′.
