摘要：

We discuss the extraction of V(cb) from BBAR --> D*l-nu(l)BAR in the context of the heavy quark symmetry. Special attention is paid to the theoretical uncertainties in the procedure of extrapolating to zero recoil introduced by choosing the shape of the Isgur-Wise function. A phenomenologically based procedure is proposed to eliminate these uncertainties.
