Limits on Production of Charmed Particles by Antiprotons and Pions

Abstract
We have searched in the mass range 1.8<M<2.5 GeV for narrow resonances produced by antiprotons and pions of momentum 12.4-15.0 GeV/c interacting in a carbon target. We present upper limits on the production cross section times branching ratio for charmed mesons decaying into two charged particles.
