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 $J/\psi \to e^+ e^-, \mu^+ \mu^-$ and $\Upsilon(1,2,3S) \to \mu^+ \mu^-$, search for $D^0-\bar{D^0}$ mixing using time dependent Dalitz plot analyses of the decay $D^0 \to K^0_S\pi^+\pi^-$, and search for the process $e^+e^- \to \Lambda_b \bar{\Lambda_b}$ near threshold are discussed.
