The yields of strange particles are calculated with the UrQMD model for p,Pb(158 AGeV)Pb collisions and compared to experimental data. The yields are enhanced in central collisions if compared to proton induced or peripheral Pb+Pb collisions. The enhancement is due to secondary interactions. Nevertheless, only a reduction of the quark masses or equivalently an increase of the string tension provides an adequate description of the large observed enhancement factors (WA97 and NA49). Furthermore, the yields of unstable strange resonances as the Λ * or the φ are considerably affected by hadronic rescattering of the decay products.

“…Almost every model started from independent, incoherent collisions between the interaction elements (hadrons or partons), and then included the effects of rescattering and coherence through string fusion, color ropes, quark droplets, interacting baryon junctions (27)(28)(29). "Independence" here means that the successive collisions of a projectile nucleon with the target nucleons do not influence each other.…”

▪ Abstract Strangeness production is a very useful diagnostic tool in finding the quark-gluon plasma. We review its uses in understanding relativistic heavy-ion collisions. A brief introduction to the main theoretical tools used in interpreting strangeness production is given, and the experimental methods used to extract the signals are discussed in detail. The experimental results from the Brookhaven AGS and CERN SPS programs are presented. We discuss the interpretation of these results, emphasizing their role in the discovery of deconfined quark matter at CERN. Future experiments at RHIC and at the CERN LHC are described.
