On Studying Charm in Nuclei through Antiproton Annihilation

Abstract

We examine the production of open charm in antiproton annihilation on finite nuclei. The enhancement of the subthreshold production cross section, even in a nucleus as light as carbon, should provide a clean signature of the reduction in the masses of these mesons in-medium. We also show that a careful analysis of the $D^{+}$ and $D^{-}$ spectra can yield important information on the cross section for $D^{\pm }N$ scattering.
