Observation of inclusive B decays to the charmed baryons Σc++ and Σc0

Description

Using data collected in the region of the Υ(4S) resonance with the CLEO II detector operating at the Cornell Electron Storage Ring, we report on evidence for the production of Σc++ and Σe0 baryons in B decays, with Σc→Λc+π. This observation is based on 77±19Σc++ and 76±21Σc0 candidates from B decays. We find the product branching fractions scrB(bar B→ΣcX)scrB(Λc+→pK-π+) for Σc=Σc++, Σc0, and Σc+ to be (2.1±0.8±0.7)x10-4, (2.3±0.8±0.7)x10-4, and less than 4.8x10-4 at 90% confidence level, respectively. A study of the Σc++ and Σc0 momentum spectra indicates that B decays to two-body final states with Σc are suppressed
