Abstract

We have studied the Cabibbo suppressed decay Λ_c⁺ → Σ⁺ K^*0(892) and the Cabibbo favored decays Λ_c⁺ → Σ⁺K⁺K^-, Λ_c⁺ → Σ⁺φ and Λ_c⁺ → ξ^*0 (Σ⁺K^-)K⁺ and measured their branching ratios relative to Λ_c⁺ → Σ⁺π⁺π^- to be (7.8 ± 1.8 ± 1.3)%, (7.1 ± 1.1 ± 1.1)%, (8.7 + 1.6 ± 0.6)% and (2.2 ± 0.6 ± 0.6)%, respectively. The first error is statistical and the second is systematic. We also report two 90% confidence level limits Γ(Λ_c⁺ → Σ^- K⁺ π⁺)/Γ(Λ_c⁺ → Σ⁺ K^*0 (892)) < 35% and Γ(Λ_c⁺ → Σ⁺K⁺K^-)_NR/Γ (Λ_c⁺ → Σ⁺π⁺π^-) < 2.8%.
