摘要：

We propose a simple parameterization for the form factors in heavy to light decays, which satisfies the heavy quark scaling laws and avoids introducing the explicit "dipole" form. The illustration is provided with the set of lattice data for B --> pi semileptonic decay. The resulting shape of the form factor also agrees with the QCD sum rule predictions.
