Interactions of charmed mesons with nucleons in the ¯

We study the possibility to measure the elastic ΦN (Φ≡J/ψ,ψ(2S), ψ(3770), χ2c) scattering cross section in the reaction ¯p+d→Φ+nsp and the elastic D(¯D)N scattering cross section in the reaction ¯p+d→D−D0psp. Our studies indicate that the elastic scattering cross sections can be determined for Φ momenta about 4–6 GeV/c and D/¯D momenta 2–5 GeV/c by selecting events with pt≥ 0.4 GeV/c for Φ's and pt(psp) ≥ 0.5 GeV/c for D/¯D-meson production.
