    "abstract": "The BUU transport model is applied to study strangeness and pion production\nin nucleus-nucleus collisions. Starting from proton induced reactions, we\nfurther investigate Si+Au, Au+Au and Pb+Pb collisions in the energy range\nbetween 2 and 40 A$\\cdot$GeV and compare with data and with other transport\ncalculations. The $q \\bar q$ annihilation, or resonance, channel simulated by\nthe string model in meson-nucleon collisions at $\\sqrt{s} \u003e 2$ GeV is\nintroduced. The importance of this channel for a good description of the\nproton-nucleus data on $K^+$ production is demonstrated. We, furthermore, show\nthat the meson-meson collisions contribute significantly to the $K \\bar K$\nproduction in heavy-ion collisions above 5 A GeV and improve an agreement with\ndata on the $K^+/\\pi^+$ ratio. Finally, we study the influence of the in-medium\nmodifications of the FRITIOF model on the pion and kaon production.",
