Abstract

We present a study of rare decay modes B+→D+Sh0, B+→D*+S h0, and B+→D+h0, where h0 denotes the neutral meson η or K0, using a data sample of (772±10)×106   BB̅ events produced at the Υ(4S) resonance. The data were collected by the Belle detector operating at the asymmetric-energy KEKB collider. We find no evidence for these decays, so we set upper limits at the 90% confidence level on the branching fractions of B+→D+ S h0, D*+ S h0, and D+h0 decay modes. Along with these rare decay modes, we report improved measurements of the color-suppressed decay branching fractions B(B̅ 0 →D0η)=(26.6±1.2±2.1)×10−5 and B(B̅ 0→D00 )=(5.6±0.5±0.2)×10−5. The first and second quoted uncertainties are statistical and systematic, respectively.
