    "abstract": "Within a hydrodynamical approach we investigate the sensitivity of single\ninclusive momentum spectra of hadrons in 158A GeV Pb+Pb collisions to three\ndifferent equations of state of nuclear matter. Two of the equations of state\nare based on lattice QCD results and include a phase transition to a\nquark-gluon plasma. The third equation of state has been extracted from the\nmicroscopic transport code RQMD under the assumption of complete local\nthermalization. All three equations of state provide reasonable fits to data\ntaken by the NA44 and NA49 Collaborations. The initial conditions before the\nevolution of the fireballs and the space-time evolution pictures differ\ndramatically for the three equations of state when the same freeze-out\ntemperature is used in all calculations. However, the softest of the equations\nof state results in transverse mass spectra that are too steep in the central\nrapidity region. We conclude that the transverse particle momenta are\ndetermined by the effective softness of the equation of state during the\nfireball expansion.",
