| 英文摘要 | A flavour-tagged decay-time-dependent amplitude analysis of b-s(0) -> (k+pi(-))(k-pi(+)) decays is presented in the k-+/-pi(-/+) mass range from 750 to 1600 mev/c(2). the analysis uses pp collision data collected with the lhcb detector at centre-of-mass energies of 7 and 8 tev, corresponding to an integrated luminosity of 3.0 fb(-1). several quasi-two-body decay modes are considered, corresponding to k-+/-pi(-/+) combinations with spin 0, 1 and 2, which are dominated by the k-0(*)(800)(0) and k-0(*)(1430)(0), the k*(892)(0) and the k-2(*)(1430)(0) resonances, respectively. the longitudinal polarisation fraction for the b-s(0) -> k-*(892)(0) (k*) over bar (892)(0) decay is measured as f(l) = 0.208 +/- 0.032 +/- 0.046, where the first uncertainty is statistical and the second is systematic. the first measurement of the mixing-induced cp-violating phase in phi(d (d) over bar)(s), in b -> d (s) over bars transitions is performed, yielding a value of phi(d (d) over bar)(s)= -0.10 +/- 0.13 (stat) +/- 0.14 (syst) rad. |
