Abstract

Branching fraction measurements using B-meson decays to KS0π+π- are presented. These measurements were obtained by analyzing a data sample of 88.9×106 Υ(4S)→BB̅ decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. Using a maximum likelihood fit, the following branching fraction results were obtained: B(B0→K0π+π-)=(43.7±3.8±3.4)×10-6, B(B0→K*+π-)=(12.9±2.4±1.4)×10-6, and B(B0→D-(→KS0π-)π+)=(42.7±2.1±2.2)×10-6. The CP violating charge asymmetry AK*π for the decay B0→K*+π- was measured to be AK*π=0.23±0.18-0.06+0.09. For all these measurements the first error is statistical and the second is systematic.
