The like-sign dimuon charge asymmetry observed by the D$\\O$ Collaboration indicates the CP-violating new physics in the $B_s-\\bar B_s$ mixing. On the other hand, LHCb observed the CP-violating asymmetry in $B_s^0\\to J/\\psi \\phi$ and $B_s^0\\to J/\\psi f_0(980)$, 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.
