Abstract

The measurement of the mixing-induced CP-violating phase ϕ_s in the B⁰_s - B⁰_s system is one of the key goals of the LHCb experiment, and provides an excellent opportunity to search for New Physics beyond Standard Model. Using Run-I data, ϕ_s has been measured in several decay channels. These proceedings briefly summarise the previous LHCb Run-I results of ϕ_s measurement, and show the most recent results obtained by analysing the decay channel B⁰_s → J/ψK⁺ K^- in the K⁺ K^- mass region above the ϕ(1020) resonance.
