Baryon distributions in heavy ion collisions at AGS energies: An experimental overview

摘要

Data on rapidity distributions of protons from the three AGS experiments E-814, E-810 and E-802 are compared on a common base to enlarge the rapidity coverage. Together they provide a unique opportunity to study the proton distributions in relativistic heavy ion reactions over the full rapidity range. Systematics of the rapidity density distributions are presented as function of centrality and mass of colliding system. Considerable stopping is achieved for the heaviest system studied, Au+Au, thus giving the means to study high-density effects in nuclear matter.
