摘要：
We present results on time-dependent CP asymmetries in f(0)(980)(-> pi(+)pi(-))KO S and B-0 -> (K+K-K0). The measurements use a data sample consisting of approximately 209(f(0)(980)(-> pi(+)pi(-))K-S(0)) and 227(B-0 -> (K+K-K0)) million B-meson pairs recorded at the Upsilon(4S) resonance with the BABAR detector at the PEP-II B-meson Factory at SLAC. From a time-dependent maximum likelihood fit, we measure for B-0 -> f(0)(980)(-> pi(+)pi(-))K-S(0),: the mixing-induced CP violation parameter S-f0K = -0.95(0.23)(+0.32) (stat) +/- 0.10(syst) and the direct CP violation parameter C-f0K = -0.24 +/- 0.31 (stat) +/- 0.15 (syst). From a simultaneous fit to B-0 -> phi K-S(0) and B-0 -> phi K-L(0) decays, we find: SphiKS0 = -SphiKL0 = +0.50 +/- 0.25 (stat)(-0.04)(+0.07) (syst) and C phi K = 0.00 +/- 0.23 (stat) +/- 0.05 (syst). For B-0 -> (K+K-KS0) decays with B-0 -> phi K-0(S) decays excluded, we find: S-KKK(no phi K-S(0)) = -0.42 +/- 0.17 (stat) +/- 0.04 (syst) and C-KKK(no phi K-0(S)) = +0.10 +/- 0.14 (stat) +/- 0.06 (syst). From the B-0 -> (K+K-KS0) decays with B-0 -> phi K-S(0) decays excluded, we extract the fraction of CP-even final states from angular moments 0.89 +/- 0.08 +/- 0.06.
