Abstract

Using 116.1 fb(-1) of data collected by the BABAR detector, we present an analysis of Xi(c)(0) production in B decays and from the c (c) over bar continuum, with the Xi(c)(0) decaying into Omega(-)K(+) and Xi(-)pi(+) final states. We measure the ratio of branching fractions B(Xi(c)(0)->Omega(-)K(+))/B(Xi(c)(0)->Xi(-)pi(+)) to be 0.294 +/- 0.018 +/- 0.016, where the first uncertainty is statistical and the second is systematic. The Xi(c)(0) momentum spectrum is measured on and 40 MeV below the Upsilon(4S) resonance. From these spectra the branching fraction product B(B ->Xi(c)(0)X)xB(Xi(c)(0)->Xi(-)pi(+)) is measured to be (2.11 +/- 0.19 +/- 0.25)x10(-4), and the cross-section product sigma(e(+)e(-)->Xi(c)(0)X)xB(Xi(c)(0)->Xi(-)pi(+)) from the continuum is measured to be (388 +/- 39 +/- 41) fb at a center-of-mass energy of 10.58 GeV.
