Abstract
The form factors for the weak currents between B and light mesons are studied by relating them to the corresponding D form factors at q(max) (2) according to HQET, by evaluating them at q(2) = 0 by QCD sum rules , and by assuming a polar q(2) dependence. The results found are consi stent with the information obtained from exclusive nonleptonic two-bod y decays and, with the only exception of A(1), with lattice calculatio ns.
