Abstract

The bounds on the form factors for B\ensuremath→\ensuremathρl\ensuremathν_l decay are studied. Constrained by lattice data and a constrained conformal mapping, more information can be obtained for the A₁(q²) form factor which dominates the decay rate at large q². Specifically, we confirm a moderately increasing behavior of this form factor.
