| 英文摘要 | The cp asymmetry in the mixing of b-s(0) and (b) over bar (0)(s) mesons is measured in proton-proton collision data corresponding to an integrated luminosity of 3.0 fb(-1), recorded by the lhcb experiment at center-of-mass energies of 7 and 8 tev. semileptonic b-s(0) and (b) over bar (s) (0) decays are studied in the inclusive mode d-s(-/+)mu(+/-)nu((-)) x-mu with the d-s(-/+) mesons reconstructed in the k+k-pi(-/+) final state. correcting the observed charge asymmetry for detection and background effects, the cp asymmetry is found to be a(sl)(s) = (0.39 +/- 0.26 +/- 0.20)%, where the first uncertainty is statistical and the second systematic. this is the most precise measurement of a(sl)(s) to date. it is consistent with the prediction from the standard model and will constrain new models of particle physics. |
