英文摘要	The decays of b (s) (0) and mesons into the j/psi k (+) k (-) final state are studied in the k (+) k (-) mass region above the i center dot(1020) meson in order to determine the resonant substructure and measure the cp-violating phase, i center dot (s) , the decay width, i" (s) , and the width difference between light and heavy mass eigenstates, delta i" (s) . 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 i center dot (s) = 119 +/- 107 +/- 34 mrad. a combination with previous lhcb measurements using similar decays into the j/psi pi (+) pi (-) and j/psi i center dot(1020) final states gives i center dot (s) = 1 +/- 37 mrad, consistent with the standard model prediction.
