First observation of inclusive B decays to the charmed strange baryons Ξc0 and Ξc+

First observation of inclusive B decays to the charmed strange baryons Ξc0 and Ξc+

Using data collected in the region of the Y(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...

Omschrijving
Samenvatting:Using data collected in the region of the Y(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(B̄ → Ξc0X)ℬ(Ξc0 → Ξ-π+ = (0.144 ± 0.048 ± 0.021) × 10-3 and ℬ(B̄ → Ξc+X)ℬ(ΞC+ → Ξ-π+π+) = (0.453 ± 0.096- 0.065+ 0.085) × 10-3.
