摘要：

The bounds on the form factors for B --> <rho l(nu)over bar>(l) decay are studied. Constrained by lattice data and a constrained conformal mapping, more information can be obtained for the A(1)(q(2)) form factor which dominated the decay rate at large q(2). Specifically, we confirm a moderately increasing behavior of this form factor.
