BABAR的无粲二体和准二体B衰变

Charmless Two-Body and Quasi-Two-Body B-decays at BABAR

Ingrid Ofte

摘要:

我们改进了对两体衰变B 0--> pi 0 pi 0,B 0--> K 0 pi 0和B 0--> K+ pi-以及准两体衰变B 0--> K_1(1270)+ pi-和B 0--> K_1(1400)+ pi-的分支分数和CP不对称性的测量。这些更新的测量结果是使用1999年至2007年间在SLAC PEP-II对撞机上收集的Y(4S)共振处获取的完整BABAR数据进行的。

英文摘要:

We present improved measurements of the branching fractions and CP asymmetries in the two-body decays B0 --> pi0 pi0, B0 --> K0 pi0 and B0 --> K+ pi- as well as the quasi two-body B0 --> K_1(1270)+ pi- and B0 --> K_1(1400)+ pi- decays. These updated measurements are made using the complete set of BABAR data taken at the Y(4S) resonance, collected between 1999 and 2007 at the PEP-II collider at SLAC.
