Outline

• Mixing

  • Phenomenology
  • Theoretical guidance
  • The new CLEO results
  • Sensitivity to compete via y=?(K?)/ ?(KK) -1

• FOCUS

  • Lots of statistics 1 million D
    • 16,500 D?KK
  • Segment target w/ little absorption
  • Great time resolution (~8% ?(K?))
  • Cerenkov system controls reflections
  • A skim w/ nearly flat acceptance
    • Candidate driven vrs topological

• FT lifetime techniques

  • Reduced proper time variable
  • Non-parametric background
  • Subtracting reflections

• CP eigenstate lifetimes

  • Cut selections
  • MC corrections
  • Results
  • Consistency of results under:
    • Various cuts
    • Various binnings
    • Various sidebands
  • How we compare to CLEO
    • Strong phase uncertainty

• Search for CP violation
