Abstract
Using data from the FOCUS experiment (FNAL-E831), we study the decay of Λc+ baryons into final states containing a Λ hyperon. The branching fractions of Λc+ into Λπ+, Λπ+π+π - and ΛK̄0K+ relative to that into pK-π+ are measured to be 0.217 ± 0.013 ± 0.020, 0.508 ± 0.024 ± 0.024 and 0.142 ± 0.018 ± 0.022, respectively. We also report new measurements of Γ(Λ c+→Σ0π+)/ ΓΛc+→Λπ+) = 1.09 ± 0.11 ± 0.19, (ΓΛc+→Σ0π+π+π -)/Γ(Λc+→Λπ +π+π-) = 0.26 ± 0.06 ± 0.09 and Γ(Λc+→Ξ(1690) 0(ΛK̄0)K+/Γ(Λ c+→ΛK̄0K+) = 0.32 ± 0.10 ± 0.04. Further, an analysis of the subresonant structure for the Λc+ → Λπ+π +π- decay mode is presented. © 2005 Elsevier B.V. All rights reserved.
