dc.description.abstract | Using 116.1 fb − 1 of data collected by the BABAR detector, we present an analysis of Ξ 0 c production in B decays and from the c ¯ c continuum, with the Ξ 0 c decaying into Ω − K + and Ξ − π + final states. We measure the ratio of branching fractions B ( Ξ 0 c → Ω − K + ) / B ( Ξ 0 c → Ξ − π + ) to be 0.294 ± 0.018 ± 0.016 , where the first uncertainty is statistical and the second is systematic. The Ξ 0 c momentum spectrum is measured on and 40 MeV below the Υ ( 4 S ) resonance. From these spectra the branching fraction product B ( B → Ξ 0 c X ) × B ( Ξ 0 c → Ξ − π + ) is measured to be ( 2.11 ± 0.19 ± 0.25 ) × 10 − 4 , and the cross-section product σ ( e + e − → Ξ 0 c X ) × B ( Ξ 0 c → Ξ − π + ) from the continuum is measured to be ( 388 ± 39 ± 41 ) fb at a center-of-mass energy of 10.58 GeV. | - |
