On the corrections to pole dominance in B {yields} {pi}l{nu}

Abstract

In the framework combining the heavy quark expansion and chiral symmetry for light quarks, we identify a class of corrections to the dominant vector meson pole diagram for B {yields} {pi}l{nu}, in the vicinity of the zero pion recoil point. We also give a qualitative estimate of these effects, using higher states exchanges with couplings constrained by current algebra and PCAC. (author). 12 refs, 1 fig.
