We show that adding final state interactions (including strangeness exchange reactions as well as the inverse reactions required by detailed balance) with a single averaged cross-section $σ=0.2$ mb, we can explain the observed hyperon enhancement in PbPb collisions at CERN SPS.6 pages, 2 eps-figuresHigh Energy Physics - Phenomenologytext
