    "abstract": "The pp -\u003e pp eta\u0027 reaction is investigated within a relativistic\nmeson-exchange model of hadronic interactions. We explore the role of nucleonic\nand mesonic, as well as the N* resonance currents, in producing eta\u0027 mesons. In\norder to learn more about the production mechanisms, new measurements in the\nenergy region far from the threshold are required.",
