Introduction to Physics
A short introduction to some current topics in  physics is presented in
order to set the stage for some results to be announced at this Workshop. After
briefly reviewing the Cabibbo-Kobayashi-Maskawa (CKM) matrix and information on
its parameters, the decays of neutral  mesons to several CP eigenstates, and
some  decays, are discussed. It is shown that progress is being
made on determination of all the angles of the unitarity triangle.Comment: 12 pages, LaTeX, 7 figures plus photo, invited talk presented at
  XXXVIII Rencontres de Moriond: Electroweak Interactions and Unified Theories,
  Les Arcs, France, March 15-22, 2003. To be published in the Proceedings. More

Exotic states of matter in heavy meson decays
The potential of decays of mesons containing heavy quarks [including 
mesons and the ] for producing final states of matter with
unusual quark configurations, such as  or ,
is investigated. The usefulness of antineutron detection in such searches is
stressed.Comment: 15 pages, 8 figures, submitted to Phys. Rev. D. References and some

Theoretical Issues in Flavor Physics
Quark and lepton flavor physics presents us with a basic question: Can we
understand the pattern of masses and mixings of the known quarks and leptons,
and how do present and proposed measurements help to advance that goal? Topics
discussed include the apparent suppression of new flavor-changing effects, the
status of quark and lepton mixing, the implications of new measurements of CP
asymmetries in heavy quark decays, the impications of forthcoming experiments
on the muon's anomalous magnetic moment and its transitions to an electron, and
what we can hope to learn from electric dipole moments.Comment: 11 pages, 3 figures, presentation at the DPF 2013 Meeting of the

Learning the weak phase from B decays
The current status of some methods to determine the weak phase  of
the Cabibbo-Kobayashi-Maskawa (CKM) matrix element  using B decays is
discussed, and comments are made on accuracy achievable in the next few years.Comment: 7 pages, 9 figures, talk given at the 9th International Conference on
  B-Physics at Hadron Machines (BEAUTY 2003), CMU, Pittsburgh, October 2003.
