AbstractThe dynamics of strange particles produced in proton-induced nuclear reactions near threshold energies has been investigated within the Lanzhou quantum molecular dynamics transport model. The in-medium modifications on particle production in dense nuclear matter are considered through corrections on the elementary cross sections via the effective mass and the mean-field potentials. It is found that the attractive antikaon-nucleon potential enhances the subthreshold (K) over bar production and influences the structure of inclusive spectra. The strangeness production is strongly suppressed in proton-induced reactions in comparison to heavy-ion collisions. The kaon-nucleon and antikaon-nucleon potentials change the structures of rapidity and transverse momentum distributions and the inclusive spectra. The measured K-/K+ ratios in collisions of C-12 + C-12, Au-197 + Au-197, p + C-12, and p + Au-197 from the KaoS Collaboration have been well explained with the inclusion of the in-medium potentials.
