Search for exclusive b → u transitions in hadronic decays of B mesons involving Ds + and Ds *+ mesons
Using 1.16 × 106 BB events collected at the γ(4S) resonance by the CLEO Collaboration at the Cornell Electron Storage Ring (CESR), we have searched for decays of B mesons to exclusive two-body hadronic final states including a Ds + or a Ds *+ meson. We obtain the 90% confidence level upper limit β (B → Ds (*)+π- + Ds *+p- + Ds (*)+π0 + Ds (*)+η + Ds (*)+p0 + Ds (*)+(ω) × β(Ds + → φπ+) < 1.8 × 10-5. We have also searched for the W-exchange decays, B0 → Ds (*)-K(*)+. © 1993.
