B+,0→ K(892)+π−, φ K(*), K+π0, K0π0, π+π−, π+ρ0, π+ρ−, π+ω η K*, η′ K and K0π+, K+π−. These charmless hadronic decay modes can probe CP violation and are sensitive to the angles α and γ of the unitarity triangle. Finally, CLEO observed many exclusive charmed decays of B mesons, including several that are sensitive to |Vcb|: B→ D(*)K*−, 0→ D*0π0 B→ Λπ−, Λπ+π−, 0→ D*0π+π+π−π−, 0→ D*ρ′−, B0→ D*−pπ+, D*−p, B→ J/Ψ φ K, B0→ D*+D*−, and B+→ 0 K+. Charm hadrons Although CLEO ran mainly near the Υ(4S) to study B mesons, it was also competitive with experiments designed to study charm hadrons. The first measurement of charm hadron properties by CLEO was the observation of the Ds. CLEO measured a mass of 1970±7 MeV, considerably lower than previous observations at 2030±60 MeV and 2020±10 MeV. CLEO discovered the DsJ(2573) and the DsJ(2463). CLEO was the first experiment to measure the doubly Cabibbo suppressed decay D0→ K+π−, and CLEO performed Dalitz analyses of D0,+ in several decay modes. CLEO studied the D*(2010)+, making the first measurement of its width and the most precise measurement of the D*-D0 mass difference. CLEO-c made many of the most accurate measurements of D meson branching ratios in inclusive channels, μ+νμ, semileptonic decays, and hadronic decays. These branching fractions are important inputs to B meson measurements at BaBar and Belle. CLEO first observed the purely leptonic decay D→μ+, which provided an experimental measure of the decay constant fDs. CLEO-c made the most precise measurements of fD+ and fDs. These decay constants are in turn a key input to the interpretation of other measurements, such as B mixing. Other D decay modes discovered by CLEO are p, ωπ+, η ρ+, η'ρ+, φρ+, η π+, η'π+, and φ l ν. CLEO discovered many charmed baryons and discovered or improved the measurement of many charmed baryon decay modes. Before BaBar and Belle began discovering new charm baryons in 2005, CLEO had discovered thirteen of the twenty known charm baryons: Ξ, Ξ(2790), Ξ(2815), Ξ, Σ(2520), Ξ(2645), Ξ(2645), and Λ(2593). Charmed baryon decay modes discovered at CLEO are Ω→ Ω−e+e; Λ→ p0η, Ληπ+, Σ+η, Σ*+η, Λ0K+, Σ+π0, Σ+ω, Λπ+π+π−π0, Λωπ+; and Ξ→Ξ0e+ e. Quarkonium Quarkonium states provide experimental input for lattice QCD and non-relativistic QCD calculations. CLEO studied the Υ system until the end of the CUSB and CUSB-II experiments, then returned to the Υ system with the CLEO
