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 $Λ_b \to X_c l \bar{\n}_l$ $(l=e,\tau )$, using the methods of heavy quark effective theory.
