Remarks on the Inclusive Decays $\Lambda_b \to X_s \gamma$ and $\Lambda_b \to X_c l \bar{\nu}_l$

Abstract

We consider the effects of quark-binding on the angular distribution and polarization characteristics of the inclusive decays $\Lambda_b \to X_s \gamma$ and $\Lambda_b \to X_c l \bar{\n}_l$ $(l=e, \tau)$, using the methods of heavy quark effective theory.
