Isgur-Wise Functions from the Mit Bag Model

Abstract

The Isgur-Wise functions for the ground state to ground state semileptonic decays involving $b\to c$ transitions are calculated from the (modified) MIT bag model. It is checked that the results for the decays $\overline{B}\to Dl\overline{\nu }$ and $\overline{B}\to D^{\ast }l\overline{\nu }$ agree well with experiment. Predictions for the decays ${\Lambda }_b\to {\Lambda }_{c}l\overline{\nu }$, ${\overline{B}}_s\to D_{s}l\overline{\nu }$ and ${\overline{B}}_s\to D_s^{\ast }l\overline{\nu }$ are given and discussed.
