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 Dà Collaboration indicates the CP-violating new physics in the Bs-B¯s mixing. On the other hand, LHCb observed the CP-violating asymmetry in Bs0âJ/ÏÏ and Bs0âJ/Ïf0(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 Bd0âÏKS, Bd0âηâ²K0, Bs0âÏÏ and Bs0âÏηâ².
