midrapidty for b = 6 fm, right: centrality dependence of v 2 at midrapidity
11.3.3 Strangeness Production
Strangeness production below the energetic threshold of the elementary production
is a process which is strongly related to the properties of the high-density region
build up during the compression phase of the reaction. The basic key is a multistep
process forming first a delta in a high energetic collision of two nucleons followed
by a collision of this delta with another nucleon in order to form a kaon-hyperon
pair. Since the delta decay is a process strongly concurring to that channel, short
mean free pathes are needed. Thus strangeness production is very sensitive on the
density reached in the reaction. For details see [10]. This is also the reason why kaon
