Summary: The authors have measured the branching fractions of the Cabibbo-suppressed decays Λ{sub c}⁺ --> Λ°K⁺ and Λ{sub c}⁺ --> Σ°K⁺ relative to the Cabibbo-allowed decay modes Λ{sub c}⁺ --> Λ°π⁺ and Λ{sub c}⁺ --> Σ°π⁺ to be 0.044 ± 0.004 (stat.) ± 0.002 (syst.) and 0.040 ± 0.005 (stat.) ± 0.004 (syst.), respectively. They also present the first observation of Λ{sub c}⁺ --> Λ°K⁺π⁺π⁻ and have measured the branching fraction relative to Λ{sub c}⁺ --> Λ°π⁺ to be 0.266 ± 0.027 (stat.) ± 0.032 (syst.). The upper limit of the branching fraction into the decay Λ{sub c}⁺ --> Σ°K⁺π⁺π⁻ relative to Λ{sub c}⁺ --> Σ°π⁺ has been measured to be < 3.9 x 10⁻² at the 90% confidence level. This analysis was performed using a data sample of 125 fb⁻¹ (integrated luminosity) collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at the Stanford Linear Accelerator Center. All results presented in this contribution are preliminary.
