Working Group 8

Tau, Charm, QCD and Two-photon Physics

Theorist Conveners: Fred Gilman, Roberto Peccei, Antonio Pich

Experimentalist Conveners: Pat Burchat, Abe Seiden

  • How can we search for "New Physics" with charm decays? (E.g., D mixing, CP violation, rare or forbidden decays)
  • How well can we measure properties of charm decays that will increase our understanding of B decays? (E.g., semileptonic decays and form factors; hadronic decay rates and studies of resonant substructure; leptonic decays)
  • Can we improve tau measurments? What can we learn from precision measurements? (E.g., lifetime, decay rates, rare decays, tau neutrino mass, CP violation, Lorentz structure, final states with kaons)
  • What can we learn in the area of QCD and two-photon physics? (E.g., meson spectroscopy, measurement of R)
