Phys. Rev. Lett. 64, 2117–2120 (1990)Exclusive and inclusive decays of B mesons into Ds mesonsReceived 15 January 1990; published in the issue dated 30 April 1990 We have studied the production of Ds mesons in the decays of B mesons at the Υ(4S) resonance. We report on the first observation of exclusive B-meson decays B->Ds-D*+, B→Ds-D+, and B→Ds-D0. We also present a new measurement of the branching ratio and the momentum spectrum for the inclusive decay B→DsX. © 1990 The American Physical Society URL:
