摘要：

We calculate the production cross sections for kaons and pi-mesons in a new hadronic fireball model, which includes all hadrons of masses below 1.3 GeV. We find that we are able to reproduce the increase in the K/pi-ratios in nucleus-nucleus collisions as compared to proton-nucleus collisions, which was experimentally observed by the E802 Collaboration at Brookhaven National Laboratory. In addition, we predict an isospin effect to be visible in these ratios.
