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.
