Dispersive Bounds on the Shape of $\overline{B} \to D^{*}l\overline\nu$ Form Factors

Dispersive constraints on the shape of the form factors which describe the exclusive decays B -> D^(*) l nu are derived by fully exploiting spin symmetry in the ground-state doublet of heavy-light mesons. The analysis includes all twenty B^(*) -> D^(*) semileptonic form factors. Heavy-quark sy...
