CLEO Results on Heavy Meson Mixing
  We discuss recent CLEO results on D0-D0bar and B0d-B0dbar mixing. The principal results are that for the D0 system, allowing for CP violations, the mixing amplitude x'<2.9% (95% C.L.), and for the B0d system, chi=0.198+-0.013+-0.014. We make projections for future sensistivity to D0-D0bar mixing, and to sin(2*beta+gamma).
