Limits on Charmed-Meson Production in e+e- Annihilation at 4.8-GeV Center-of-Mass Energy

Data from e⁺e^- annihilation into hadrons at 4.8 GeV center-of-mass energy were used to search for charmed mesons in the mass range 1.5 to 4.0 GeV/c². We looked for narrow peaks in the invariant-mass distributions for K^-/+π^+/-, K_s⁰π⁺π^-, π⁺π^-, K⁺K^-, K^-/+π^+/-π^+/-, K_s⁰π^+/-, K_s⁰K^+/-, and π⁺π^-π^+/-. We present upper limits for the inclusive production cross section times the branching ratio for charmed mesons having these decay modes.
