Abstract

The bounds on the form factors for B→ρℓνℓB \to \rho \ell \nu_\ell decay are studied. Constrained by lattice data and a constrained conformal mapping, the more informations can be obtained for A1(q2)A_1(q^2) form-factor which dominates the decay rate at large q2q^2. Specifically, we confirm a moderately increasing behavior of this form factor.
