Abstract

The decays of B_s ⁰and B¯s0 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, ϕ_s, the decay width, Γ_s, and the width difference between light and heavy mass eigenstates, ΔΓ_s. A decay-time dependent amplitude analysis is employed. The data sample corresponds to an integrated luminosity of 3 fb⁻¹produced in 7 and 8 TeV pp collisions at the LHC, collected by the LHCb experiment. The measurement determines ϕ_s= 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 ϕ_s= 1 ± 37 mrad, consistent with the Standard Model prediction.[Figure not available: see fulltext.]
