Progress in leptonic and semileptonic decays in lattice QCD

Abstract

The status of lattice calculations of heavy quark phenomenology is reviewed. Particular emphasis is placed on the understanding and control of the calculational uncertainties. The ensuing implications for constraining the CKM matrix elements are discussed.Comment: 7 pages, talk given at DPF'99 Conference, Jan. 5-9 1999, Los Angeles, C
