Combined nonrelativistic constituent quark model and heavy quark effective theory study of semileptonic decays of Λ_b and Ξ_b baryons

C. Albertus, E. Hernandez, J. Nieves

We present the results of a nonrelativistic constituent quark model study of the semileptonic decays ${\Lambda }_b^0\to {\Lambda }_c^{+}{l}^{-}{\bar{\nu }}_l$ and ${\Xi }_b^0\to {\Xi }_c^{+}{l}^{-}{\bar{\nu }}_l$. We work…
