Abstract
We discuss the possible corrections of some recent calculations on the form factors which parametrize the matrix element of the decays B(D) --> pi/nu. These calculations are based on the assumption that the B( D) pole contribution is fully dominant near zero recoil. By using the Bethe-Salpeter approach, we calculate some low-lying state pole terms predicted by the quark model. The numerical results are obtained to t he next-leading order of the 1/M expansion.
