Abstract

Direct observations of the semileptonic decay of Λ_c⁺ in the decay channels Λ_c⁺→Λe⁺X and Λ_c⁺→Λμ⁺X have been made using the ARGUS detector at the DORIS II e⁺e^- storage ring. The cross section times branching ratio were found to be σ(e⁺e^-→Λ_c⁺ X)·BR(Λ_c⁺→Λe⁺ X)=4.20±1.28±0.71 pb and σ(e⁺e^-→Λ_c⁺ X)·BR(Λ_c⁺→Λμ⁺X)=3.91±2.02±0.90 pb.
