    "abstract": "The production of antiprotons in $pp$ collisions is investigated close to\nthreshold where experimental data about the total cross section are not\navailable. We analyze the latter reaction within the LUND string model for\ninclusive $\\bar{p}$ production and within the framework of a one-boson exchange\nmodel for the exclusive reaction $pp \\rightarrow ppp\\bar{p}$. The application\nof our new results to the analysis of subthreshold antiproton production in $d\n+ p$ and $d + d$ collisions shows cross sections that are much lower than\nexpected before. Nevertheless, the comparison of experimental $\\bar{p}$\ndifferential cross sections from $d +p$ and $d + d$ is expected to provide\nvaluable information about a nonnucleonic component in the deuteron\nwavefunction.",
