Description
Using 116.1 fb-1 of data collected by the BABAR detector, we present an analysis of Ξc0 production in B decays and from the cc continuum, with the Ξc0 decaying into Ω-K+ and Ξ-π+ final states. We measure the ratio of branching fractions B(Ξc0→Ω-K+)/B(Ξc0→Ξ-π+) to be 0.294±0.018±0.016, where the first uncertainty is statistical and the second is systematic. The Ξc0 momentum spectrum is measured on and 40 MeV below the Υ(4S) resonance. From these spectra the branching fraction product B(B→Ξc0X)xB(Ξc0→Ξ-π+) is measured to be (2.11±0.19±0.25)x10-4, and the cross-section product σ(e+e-→Ξc0X)xB(Ξc0→Ξ-π+) from the continuum is measured to be (388±39±41) fb at a center-of-mass energy of 10.58 GeV
