Abstract: 
Transverse hadron spectra from proton-proton, proton-nucleus and nucleus-nucleus collisions from 2 A.GeV to 21.3 A.TeV are investigated within two independent transport approaches (HSD and UrQMD). For central Au+Au (Pb+Pb) collisions at energies above E-lab similar to 5 A.GeV, the measured K+/- transverse mass spectra have a larger inverse slope parameter than expected from the default calculations. The additional pressure - as supported by lattice QCD calculations at finite quark chemical potential mu(q) and temperature T might be generated by strong interactions in the early pre-hadronic/partonic phase of central Au+Au (Pb+Pb) collisions [1].
