Abstract
We are studying a variety of semileptonic decays of heavy-light mesons in a n effort to improve the determination of the heavy-quark Standard-Model CKM matrix elements. Our fermion action is a novel, improved "fat" clover acti on that promises to reduce problems with exceptional configurations. Dynami cal sea quarks are included in a mixed approach, i.e. we use staggered sea quarks and fat-clover valence quarks. Here we report preliminary results.
