HYDRODYNAMIC SIMULATIONS OF ¹⁶<font>O</font>+²⁰⁸<font>Pb</font> COLLISIONS AT 200 <font>GeV</font>/N

Abstract

We investigate collisions of 16 O with 208 Pb at a bombarding energy of 200 GeV /N in the lab frame. Our basis is an ideal, one-fluid 3-D hydrodynamics model. Several equations of state are used to study the qualitative relation between final baryon rapidity distributions and the stiffness of the EOS. We find that 75% of the baryonic matter lies within one unit of the initial target rapidity, in qualitative agreement with recent experimental data. In addition, our calculation is able to reproduce the integrated value of the dE T /dy distribution that is observed experimentally.
