Beschreibungen/Notizen

• In this report, we discuss the discovery of Ξ c ( 3055 ) 0 , observed by its decay into the final-state Λ D0 , and present the first observation and evidence of the decays of Ξ c ( 3055 ) + and Ξ c ( 3080 ) + into Λ D+ . Furthermore, we perform a combined analysis of the Λ D+ with the Σ c++K- and Σ c*++K- decay modes to measure the ratios of branching fractions, masses and widths with improved accuracy. We measure the ratios of branching fractions B ( Ξ c ( 3055 ) + → Λ D+ ) / B ( Ξ c ( 3055 ) + → Σ c++K- ) =5.09±1.01±0.76 , B ( Ξ c ( 3080 ) + → Λ D+ ) / B ( Ξ c ( 3080 ) + → Σ c++K- ) = 1.29±0.30±0.15 , and B ( Ξ c ( 3080 ) + → Σ c*++K- ) / B ( Ξ c ( 3080 ) + → Σ c++K- ) =1.07±0.27±0.04 , where the uncertainties are statistical and systematic. The analysis is performed using a 980fb-1 data sample collected with the Belle detector at the KEKB asymmetric-energy e+e- collider.
