Abstract

One of the main goals of the LHCb experiment is to determine the mixing-induced CP violating phase ϕ_s in b → ccs transitions. Assuming the Standard Model, ϕ_s is precisely predicted, hence new physics could easily affect the measurement. The most precise single measurement using B⁰_s → J/ψK⁺K^- data collected in 2015 and 2016 is presented along with a total combined value including all LHCb ϕ_s^ccs analyses. The result is further combined with Tevatron and other LHC experimental results.
