Abstract

The determination 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. Using several B⁰_s decay modes it has been measured by the LHCb collaboration exploiting the Run I data set. The first observation of the B⁰_s → η_cϕ and B⁰_s → η_cπ⁺π^- decay modes which can be used to measure ϕ_s with Run II data is presented.
