Abstract
We present measurements of the masses and decay widths of the baryonic states and using a data sample corresponding to an integrated luminosity of collected with the Belle detector at the KEKB asymmetric-energy collider operating at the resonance. We report the mass differences with respect to the baryon and the decay widths where the first uncertainties are statistical and the second are systematic. The isospin mass splittings are measured to be and . These results are the most precise to date.
