Abstract

We report a measurement of the Ξ_c⁺ and Ξ_c⁰ baryon masses, and the branching ratios for various Ξ_c decays, using 140 fb^-1 of data collected by the Belle experiment at the KEKB e⁺e^- collider. The mass splitting m_Ξc0 - m_Ξc+ is found to be 2.9 ± 0.5 MeV/c²; this measurement is three times as precise as the current world average. We measure the branching ratios Γ(Ξ_c ⁺ → ΛK^-π⁺π⁺)/ Γ(Ξ_c⁺ → Ξ ^-π⁺π⁺) = 0.32 ± 0.03 ± 0.02 and Γ(Ξ_c⁰ → pK^-k ^-π⁺)/Γ(Ξ_c⁰ → Ξ^-π⁺) = 0.33 ± 0.03 ± 0.03, with improved precision, and measure Γ(Ξ_c⁺ → p K_S⁰K_S⁰) /Γ(Ξ_c⁺ → Ξ ^-π⁺π⁺) = 0.087 ± 0.016 ± 0.014, Γ(Ξ_c⁰ ΛK ^-π⁺)/Γ(Ξ_c⁰ → Ξ^-π⁺) = 1.07 ± 0.12 ± 0.07 and Γ(Ξ_c⁰ → ΛK_S ⁰)/Γ(Ξ_c⁰ → Ξ ^-π⁺) = 0.21 ± 0.02 ± 0.02 for the first time.
