Abstract

Determination of the mixing-induced C ⁣PC\!P-violating phase ϕs\phi_{s} and decay width difference ΔΓs\Delta\Gamma_{s} in bˉcˉcsˉ\bar{b}\to\bar{c}c\bar{s} decays is one of the main goals of the LHCb experiment. Thanks to the precise prediction of the ϕs\phi_{s} value within the Standard Model, it represents an excellent probe to search for new physics. The measurements of ϕs\phi_{s} and ΔΓs\Delta\Gamma_{s} at LHCb are reviewed including results from the 3.0~fb1^{-1} dataset accumulated during 2011-2012. Further measurement improvement is expected from the inclusion of results obtained using decay modes with smaller branching fraction.
