Title: Review of SIS experimental results on strangeness
Abstract: A review of meson emission in heavy-ion collisions at incident energies around 1-2 A GeV is presented. It is shown how the shape of the spectra and the various particle yields vary with system size, with centrality and with incident energy. A statistical model assuming thermal and chemical equilibrium and exact strangeness conservation (i.e. strangeness conservation per collision) explains most of the observed features.
