Pb+Pb collisions and in p+p minimum bias collisions [100]

nucleus-nucleus collisions at
√
s = 17.3 GeV, relative to the p+p reference at the same energy
scaled by N W (= N part ). The NA49 data refer to total 4π yields [116]. Closed lines represent the
inverse strangeness suppression factors from ref. [119], at this energy
