Abstract
We introduce a new method for selecting exclusive semileptonic charmless B-decays in the presence of a large background. The method can be applied to charged and neutral B-mesons decaying into any exclusive neutral or charged hadronic final state. The method is designed for high luminosity $\eplemi$ colliders operating at the . It employs an improved partial reconstruction technique for $\Dstar$-mesons and a novel 0-C event fit to both B-meson's decay products resulting in the kinematics of all particles (including neutrinos) in the event. The charged lepton energies are accessible from $1.0 \GeV$ to the kinematic limit.
