We present an analysis of inclusive Omega(0)(c) baryon production and decays in 230.5 fb(-1) of data recorded with the BABAR detector. Omega(0)(c) baryons are reconstructed in four final states (Omega(-)pi(+), Omega(-)pi(+)pi(0), Omega(-)pi(+)pi(+)pi(-), Xi K--(-)pi(+)pi(+)) and the corresponding ratios of branching fractions are measured. We also measure the momentum spectrum in the e(+)e(-) center-of-mass frame. From the spectrum, we observe Omega(0)(c) production from B decays and in c (c) over bar events, and extract the two rates of production.

Abstract

We present an analysis of inclusive Omega(0)(c) baryon production and decays in 230.5 fb(-1) of data recorded with the BABAR detector. Omega(0)(c) baryons are reconstructed in four final states (Omega(-)pi(+), Omega(-)pi(+)pi(0), Omega(-)pi(+)pi(+)pi(-), Xi K--(-)pi(+)pi(+)) and the corresponding ratios of branching fractions are measured. We also measure the momentum spectrum in the e(+)e(-) center-of-mass frame. From the spectrum, we observe Omega(0)(c) production from B decays and in c (c) over bar events, and extract the two rates of production.
