摘要
利用1999-2004年间在PEP-II B工厂用BABAR探测器收集的2.32亿个事件样本,我们研究了衰变,其中,、、(非CP末态);、(CP+本征态);、和(CP-本征态)。我们测量了对CKM幺正三角形角度γ敏感的四个观测量:部分速率电荷不对称性和B衰变在CP±与非CP衰变中的分支比之比:(统计)(系统),(统计)(系统),(统计)(系统),(统计)(系统)。

7 pages, 1 figure, published in Physical Review D Rapid Communications. The title is more accurate. A better definition of the R_CP observables is used. The cartesian coordinates are introduced at the beginning of the paper. 4 more theoretical references are given
