2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/36864We 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).Parallel session talk at ICHEP 2000 in Osaka; 3 pages, 3 color figures; LaTeX2e using ws-p10x7.clsHigh Energy Physics - ExperimentHigh Energy Physics - Phenomenologytext
