| 摘要: | 摘要： Measurements of midrapidity charged-particle multiplicity distributions, dNch/dη, and midrapidity transverse-energy distributions, dET/dη, are presented for a variety of collision systems and energies. Included are distributions for Au+Au collisions at √sNN=200, 130, 62.4, 39, 27, 19.6, 14.5, and 7.7 GeV, Cu+Cu collisions at √sNN=200 and 62.4 GeV, Cu+Au collisions at √sNN=200 GeV, U+U collisions at√sNN=193 GeV, d+Au collisions at √sNN=200 GeV, He3+Au collisions at √sNN=200 GeV, and p+p collisions at √sNN=200 GeV. We present centrality-dependent distributions at midrapidity in terms of the number of nucleon participants, Npart, and the number of constituent quark participants, Nqp. For all A+A collisions down to √sNN=7.7 GeV, we observed that the midrapidity data are better described by scaling with Nqp than scaling with Npart. Finally, our estimates of the Bjorken energy density, εBJ, and the ratio of dET/dη to dNch/dη are presented, the latter of which is seen to be constant as a function of centrality for all systems.
