$B \to D \ell \nu$ and $B \to D^* \ell \nu$ Form Factors at Zero-Recoil (talk)
Abstract: We update Fermilab's model independent calculation of ${\cal F}_{B \to D}(1)$,  the zero-recoil  $B \to D  \ell  \nu$ form  factor, needed to extract $|V_{cb}|$ from experiment. Extending our method to the vector mode, we determine the $B \to D^* \ell \nu$  form factor, ${\cal F}_{B\to D^*}(1)$.
