Measurements of neutral B decay branching fractions to K^0_Sπ^+π^- final states and the charge asymmetry of B^0 → K^(*+)π^-
Chicago
Abstract
We analyze the decay B^0 → K^0_Sπ^+π^- using a sample of 232 × 10^6 Υ(4S) → BB̅ decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. A maximum likelihood fit finds the following branching fractions: B(B^0 → K^0π^+π^-)=(43.0 ± 2.3 ± 2.3) × 10^(-6), B(B^0 → f_0(→ π^+π^-)K^0)=(5.5 ± 0.7 ± 0.5 ± 0.3)×10^(-6) and B(B^0→K^(*+)π^-)=(11.0 ± 1.5 ± 0.5 ± 0.5)×10^(-6). For these results, the first uncertainty is statistical, the second is systematic, and the third (if present) is due to the effect of interference from other resonances. We also measure the CP-violating charge asymmetry in the decay B^0 → K^(*+)π^-, A_(K*π) = -0.11 ± 0.14 ± 0.05.
