英文摘要A time-dependent angular analysis of b-s(0) -> psi(2s)phi decays is performed using data recorded by the lhcb experiment. the data set corresponds to an integrated luminosity of 3.0fb(-1) collected during run 1 of the lhc. the cp-violating phase and decay-width difference of the b-s(0) system are measured to be phi(s)=0.23(-0.28)(+0.29)+/- 0.02rad and delta gamma(s)=0.066(-0.044)(+0.041)+/- 0.007ps(-1), respectively, where the first uncertainty is statistical and the second systematic. this is the first time that phi s and delta gamma s have been measured in a decay containing the psi(2s) resonance.
