Abstract

Absolute branching fractions for the Dl3 and Dl4 decays D+K» 0e+e, D+K» +0, D+K» *0e+e, and D0K*-e+e are determined using completely reconstructed DD» events at the (3770). Reconstructed D0K-e+e decays are used to determine the pole mass of the f4(q2) form factor. Resonant K* production dominates the process DKe; the K* polarization is measured. Limits on several Cabibbo-suppressed channels are evaluated. A global fit imposing isospin symmetry is performed to the measured exclusive and inclusive semileptonic D0 and D+ branching fractions to obtain an improved set of branching fractions.
