Abstract

We have studied the Cabibbo suppressed decay Λc+ → Σ+ K*0(892) and the Cabibbo favored decays Λc+ → Σ+K+K-, Λc+ → Σ+φ and Λc+ → ξ*0 (Σ+K-)K+ and measured their branching ratios relative to Λc+ → 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(Λc+ → Σ- K+ π+)/Γ(Λc+ → Σ+ K*0 (892)) < 35% and Γ(Λc+ → Σ+K+K-)NR/Γ (Λc+ → Σ+π+π-) < 2.8%.
