Charged-particle multiplicity at mid-rapidity in Au-Au collisions at relativistic heavy-ion collider

Silvermyr, David LU and Collaboration, PHENIX (2003) In Pramana 60(5). p.983-986
Abstract
The particle density at mid-rapidity is an essential global variable for the characterization of nuclear collisions at ultra-relativistic energies. It provides information about the initial conditions and energy density reached in these collisions. The pseudorapidity densities of charged particles at mid-rapidity in Au+Au collisions at roots(NN) 130 and 200 GeV at RHIC (relativistic heavy ion collider) have been measured with the PHENIX detector. The measurements were performed using sets of wire-chambers with pad readout in the two central PHENIX tracking arms. Each arm covers one quarter of the azimuth in the pseudorapidity interval eta < 0.35. Data is presented and compared with results from proton-proton collisions and... (More)
