We present measurements of the branching fractions for the three-body decays B0→D(*)∓K0π± and their resonant submodes B0→D(*)∓K*± using a sample of approximately 88×106 BB̅ pairs collected by the BABAR detector at the SLAC PEP-II asymmetric energy storage ring. We measure: B(B0→D∓K0π±)=(4.9±0.7stat±0.5syst)×10-4, B(B0→D*∓K0π±)=(3.0±0.7stat±0.3syst)×10-4, B(B0→D∓K*±)=(4.6±0.6stat±0.5syst)×10-4, B(B0→D*∓K*±)=(3.2±0.6stat±0.3syst)×10-4. From these measurements we determine the fractions of resonant events to be f(B0→D∓K*±)=0.63±0.08stat±0.04syst and f(B0→D*∓K*±)=0.72±0.14stat±0.05syst.

Abstract

We present measurements of the branching fractions for the three-body decays B0→D(*)∓K0π± and their resonant submodes B0→D(*)∓K*± using a sample of approximately 88×106 BB̅ pairs collected by the BABAR detector at the SLAC PEP-II asymmetric energy storage ring. We measure: B(B0→D∓K0π±)=(4.9±0.7stat±0.5syst)×10-4, B(B0→D*∓K0π±)=(3.0±0.7stat±0.3syst)×10-4, B(B0→D∓K*±)=(4.6±0.6stat±0.5syst)×10-4, B(B0→D*∓K*±)=(3.2±0.6stat±0.3syst)×10-4. From these measurements we determine the fractions of resonant events to be f(B0→D∓K*±)=0.63±0.08stat±0.04syst and f(B0→D*∓K*±)=0.72±0.14stat±0.05syst.
