Abstract: 

The production of antiprotons in proton-nucleus and nucleus-nucleus reactions is calculated within the relativistic BUU approach employing proper selfenergies for the baryons and antiprotons and treating the p annihilation nonperturbatively. The differential cross section for the antiprotons is found to be very sensitive to the p selfenergy adopted. A detailed comparison with the available experimental data for p-nucleus and nucleus-nucleus reactions shows that the antiproton feels a moderately attractive mean-field at normal nuclear matter density ϱ₀ which is in line with a dispersive potential extracted from the free annihilation cross section.
