Abstract

Using data collected in the region of the γ\(4S\) resonance with the CLEO II detector operating at the Cornell Electron Storage Ring (CESR), we present the first observation of B mesons decaying into the charmed strange baryons Ξc0 and Ξc+. We find 79+/-27 Ξc0 and 125+/-28 Ξc+ candidates from B decays, leading to product branching fractions of B\(B¯c0X\)B\(c0⤏Ξ-π+\) = \(0.144+/-0.048+/-0.021\)×10-3 and B\(B¯⤏Ξ+cX\)B\(Ξ+C⤏Ξ-π+π+\) = \(0.453+/-0.096+ 0.085- 0.065\)×10−3.
