Abstract
A search for inclusive non-DD decays of the $\Psi\sp{\prime\prime}$(3770) is performed in a sample of 9.56 $\pm$ 0.48 pb$\sp{-1}$ collected by the Mark III detector at the SPEAR storage ring, at the Stanford Linear Accelerator Center. To be more specific, a search for inclusive p, $\bar \Lambda$, and $\phi$ decay modes of the $\Psi\sp{\prime\prime}$(3770) is performed in this data sample. Backgrounds due to the decays of the radiatively produced $\Psi\sp\prime$(3686) are subtracted. Also backgrounds due to the production of the same final state by nonresonant e$\sp+$e$\sp-$ annihilation are subtracted. After further background subtractions from D meson decays and particle misidentifiction and efficiency corrections no events are seen and upper limits are placed for each one of these decay channels.
