Form factors of the semileptonic decays {ital B}({ital D}){r_arrow}{pi}+{ital l}{nu} near zero recoil
- International Centre of Theoretical Physics, P.O. Box 586, Trieste 34100 (Italy)
We discuss the possible corrections of some recent calculations on the form factors which parametrize the matrix element of the decays {ital B}({ital D}){r_arrow}{pi}{ital l}{nu}. These calculations are based on the assumption that the {ital B}{sup {asterisk}}({ital D}{sup {asterisk}}) 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 the next-leading order of the 1/{ital M} expansion. {copyright} {ital 1996 The American Physical Society.}
