| Abstract: | : The decays of B0 s and B 0 s mesons into the J/ψK+K− final state are studied in the K+K− mass region above the φ(1020) meson in order to determine the resonant substructure and measure the CP-violating phase, φs, the decay width, Γs, and the width difference between light and heavy mass eigenstates, ∆Γs. A decay-time dependent amplitude analysis is employed. The data sample corresponds to an integrated luminosity of 3 fb−1 produced in 7 and 8 TeV pp collisions at the LHC, collected by the LHCb experiment. The measurement determines φs = 119 ± 107 ± 34 mrad. A combination with previous LHCb measurements using similar decays into the J/ψπ+π − and J/ψφ(1020) final states gives φs = 1 ± 37 mrad, consistent with the Standard Model prediction |
