Heavy Quark Decays

Abstract

The status of heavy-quark decays as of summer 1999 is reviewed. New measurements of semileptonic B decays from LEP and from CLEO are reported and the status of determining the CKM parameters |Vcb| and |Vub| is assessed. Rare charmless hadronic B decays are reviewed, including the first observation of B->pi pi from CLEO. First attempts to measure CP asymmetries in rare decays are described. The implications of all of the data for our understanding of the Standard Model are briefly assessed.
