摘要：

In the chiral limit and as mb, the decay B»+e» would be dominated near zero pionic recoil by the effects of the B* resonance. We examine the influence of this mechanism on the B»Xe»e electron spectrum in the region near the end point which is important for the determination of the Kobayashi-Maskawa matrix element Vub. © 1990 The American Physical Society.
