• CHARMED-BARYON

Using a data sample of 980 fb(-1) of e(+)e(-) annihilation data taken with the Belle detector operating at the KEKB asymmetric-energy e(+)e(-) collider, we report the results of a study of the decays of the Omega(0)(c) charmed baryon into hadronic final states. We report the most precise measurements to date of the relative branching fractions of the Omega(0)(c) into Omega(-)pi(+)pi(0), Omega(-)pi(+)pi(-)pi(+), Xi K--(-)pi(+)pi(+), and Xi K-0(-)pi(+), as well as the first measurements of the branching fractions of the Omega(0)(c) into Xi(-)(K) over bar (0)pi(+), Xi(0)(K) over bar (0), and Lambda(K) over bar (0)(K) over bar (0), all with respect to the Omega(-)pi(+) decay. In addition, we investigate the resonant substructure of these modes.
