    "abstract": "The production of antiprotons in proton-nucleus and nucleus-nucleus reactions\nis calculated within the relativistic BUU approach employing proper\nselfenergies for the baryons and antiprotons and treating the p-bar\nannihilation nonperturbatively. The differential cross section for the\nantiprotons is found to be very sensitive to the p-bar selfenergy adopted. A\ndetailed comparison with the available experimental data for p-nucleus and\nnucleus-nucleus reactions shows that the antiproton feels a moderately\nattractive mean-field at normal nuclear matter density which is in line with a\ndispersive potential extracted from the free annihilation cross section.",
