Improved bounds for the slope and curvature of $\overline{B}$ --> D$^{*}$ l$\overline{\nu}$ form factors

We derive a theoretically allowed domain for the slope \widehat\varrho^2 and curvature \widehat c of the physical form factor appearing in the decay \bar B\to D^*\ell\bar\nu. Using heavy-quark symmetry, we relate this function to a particular \bar B \to D form factor free of ground-state B_c poles b...
