| Abstract: | We present results from the PHOBOS experiment on charged hadron production over a large range in
, from Data from d + Au collisions at
GeV and Au + Au collisions at
and 200 GeV are shown. The data indicate that in Au + Au collisions a strongly interacting state of matter is formed, that
appears qualitatively different from the system formed in pp or d + Au collisions. The systematics of particle production
in d + Au and Au + Au collisions exhibit remarkably simple scaling rules, including an apparent factorization of the energy
and centrality dependence over a wide range of collision energies.
