New results from CLEO

Abstract

We present recent results from the CLEO Collaboration. The data used were collected from 1995 untill now at the Cornell Electron-positron Storage Ring (CESR). Measurements of the leptonic branching fractions for $J/ψ\to e^+ e^-, μ^+ μ^-$ and $Υ(1,2,3S) \to μ^+ μ^-$, search for $D^0-\bar{D^0}$ mixing using time dependent Dalitz plot analyses of the decay $D^0 \to K^0_Sπ^+π^-$, and search for the process $e^+e^- \to Λ_b \bar{Λ_b}$ near threshold are discussed.
