The measurement of the mixing-induced CP-violating phase ϕs in the B0s - B0s system is one of the key goals of the LHCb experiment. It has been measured at the LHCb collaboration exploiting the Run I data set and using several decay channels. In particular, the most recent Run I result has been obtained analyzing B0s → J/ψK+K- candidates in the mass region above the ϕ(1020) resonance. Despite the large improvements in the sensitivity of ϕs during the last decade, the precision is still limited by the available statistics.
