Abstract
We present a measurement of the Cabibbo-Kobayashi-Maskawa matrix element and the form-factor slope in decays based on events recorded at the resonance with the BABAR detector. decays are selected in events in which a hadronic decay of the second meson is fully reconstructed. We measure and , along with the differential decay distribution in decays. We then determine and , where is the hadronic form factor at the point of zero recoil.
