Abstract
We report the discovery of Ξc(3055)0, observed by its decay into the final-state ΛD0, and present the first observation and evidence of the decays of Ξc(3055)+ and Ξc(3080)+ into ΛD+. We also perform a combined analysis of the ΛD+ with the Σc++K- and Σc∗++K- decay modes to measure the ratios of branching fractions, masses and widths with improved accuracy. We measure the ratios of branching fractions B(Ξc(3055)+→ΛD+)/B(Ξc(3055)+→Σc++K-)=5.09±1.01±0.76, B(Ξc(3080)+→ΛD+)/B(Ξc(3080)+→Σc++K-)=1.29±0.30±0.15, and B(Ξc(3080)+→Σc∗++K-)/B(Ξc(3080)+→Σc++K-)=1.07±0.27±0.04, where the uncertainties are statistical and systematic. The analysis is performed using a 980 fb-1 data sample collected with the Belle detector at the KEKB asymmetric-energy e+e- collider.
