Observation of New Hadronic $\psi (2S)$ Decays at CLEO

Abstract

Using 5.46 pb${}^{-1}$ of $e^{+}{e}^{-}$ annihilation data collected at the $\psi (2S)$ with the CLEO detector we have observed a variety of new hadronic decay modes of the $\psi (2S)$. A comprehensive set of branching ratios and upper limits is presented.
