Abstract

We calculate the two body Cabibbo allowed non-leptonic decays of charmed baryons Λ_c and Ξ_c which involve transitions of a heavy quark to a light quark. We use data on the Cabbibo favoured non-leptonic decays Λ_c → Λπ⁺ and Λ_c → Σ⁺ π⁰ to obtain information on the form factors in the c → s transition. We also calculate the decay Λ_c → p ϕ. Using HQET the information on form factors from the c → s transition is used to model the form factors in b → s transition which are then used in the study of Λ_b → J/ ψΛ decay.
