    "abstract": "Data from KEK on subthreshold antiproton as well as on charged pion and kaon\nproduction in pC, dC and $\\alpha$C reactions at energies between 3.5 and 12.0 A\nGeV are described for the first time within a unified approach. We use a model\nwhich considers a nuclear reaction as an incoherent sum over collisions of\nvarying numbers of projectile and target nucleons. It samples complete events\nand thus allows for the simultaneous consideration of all final particles\nincluding the decay products of the nuclear residues. The enormous enhancement\nof the antiproton cross section as well as the moderate increase of meson\nproduction in dC and $\\alpha$C compared to pC reactions is well reproduced. In\nour approach, the observed enhancement near the production threshold is mainly\ndue to the contributions from the interactions of few-nucleon groups.",
