Abstract:
We calculate the two body Cabibbo allowed non-leptonic decays of charmed baryons Λc\Lambda_c and Ξc\Xi_c which involve transitions of a heavy quark to a light quark. We use data on the Cabbibo favoured non-leptonic decays Λc→Λπ +\Lambda_c \rightarrow \Lambda \pi~{+} and Λc→Σ +π 0\Lambda_c \rightarrow \Sigma~{+} \pi~{0 } to obtain information on the form factors in the c→sc \rightarrow s transition. We also calculate the decay Λc→pϕ\Lambda_c \rightarrow p \phi. Using HQET the information on form factors from the c→sc \rightarrow s transition is used to model the form factors in b→sb \rightarrow s transition which are then used in the study of Λb→J/ψΛ\Lambda_b \rightarrow J/ \psi \Lambda decay.
