Non-Leptonic two body decays of Charmed and Λ_b Baryons

Abstract

We calculate the two body Cabibbo allowed non-leptonic decays of charmed baryons ${\Lambda }_c$ and ${\Xi }_c$ which involve transitions of a heavy quark to a light quark. We use data on the Cabbibo favoured non-leptonic decays ${\Lambda }_c\to \Lambda {\pi }^{+}$ and ${\Lambda }_c\to {\Sigma }^{+}{\pi }^0$ to obtain information on the form factors in the $c\to s$ transition. We also calculate the decay ${\Lambda }_c\to p\varphi$. Using HQET the information on form factors from the $c\to s$ transition is used to model the form factors in $b\to s$ transition which are then used in the study of ${\Lambda }_b\to J/\psi \Lambda$ decay.
