    "abstract": "The antikaon production cross section from nucleon-nucleon reactions near\nthreshold is studied in a meson exchange model. We include both pion and kaon\nexchange, but neglect the interference between the amplitudes. In case of pion\nexchange the antikaon production cross section can be expressed in terms of the\nantikaon production cross section from a pion-nucleon interaction, which we\ntake from the experimental data if available. Otherwise, a $K^*$-resonance\nexchange model is introduced to relate the different reaction cross sections.\nIn case of kaon exchange the antikaon production cross section is related to\nthe elastic $KN$ and $\\bar KN$ cross sections, which are again taken from\nexperimental measurements. We find that the one-meson exchange model gives a\nsatisfactory fit to the available data for the $NN\\to NNK\\bar K$ cross section\nat high energies. We compare our predictions for the cross section near\nthreshold with an earlier empirical parameterization and that from phase space\nmodels.",
