We explore the possibility to measure the elastic and inelastic ωN cross section in p +d→d+ω +p sp and 8 p +A reactions. Our studies indicate that the elastic scattering cross sections can be determined for ω momenta above 2 1 GeV/c in p +d reactions by gating on high proton spectator momenta whereas the ωN absorption cross section down 0 to low relative ω momenta is most effectively studied in p +A reactions at beam energies 2.0–2.7 GeV. 0 1 PACS. 13.75.Cs Nucleon-nucleon interactions – 25.40.-h Nucleon-induced reactions – 25.10.+s Nuclear reactions 9 involving few-nucleon systems – 11.80.Fv Eikonal approximation – 24.10.Lx Monte Carlo simulations 9 / h t- 1 Introduction widely differ such that related experiments will have to clarify l the situation. c u The ω-meson properties at finite nuclear density have become Moreover, the amplitude for ω-meson production in proton- n of recent
