Energy dependence of transverse momentum fluctuations in Pb[plus]Pb collisions at the CERN Super Proton Synchrotron (SPS) at 20A to 158A GeV
(American Physical Society, 2009-04)
Results are presented on event-by-event fluctuations of transverse momenta pT in central Pb[plus]Pb interactions at 20A, 30A, 40A, 80A, and 158A GeV. The analysis was performed for charged particles at forward center-of-mass ...
Scaling properties in bulk and p[subscript T]-dependent particle production near midrapidity in relativistic heavy ion collisions
(American Physical Society, 2009-08)
The centrality dependence of the midrapidity charged-particle multiplicity density (|η|<1) is presented for Au+Au and Cu+Cu collisions at RHIC over a broad range of collision energies. The multiplicity measured in the Cu+Cu ...
System-size dependence of Lambda and Xi production in nucleus-nucleus collisions at 40A and 158A GeV measured at the CERN Super Proton Synchrotron
(American Physical Society, 2009-09)
Results on Lambda, Lambda[over-bar], and Xi- production in centrality selected Pb+Pb reactions at 40A and 158A GeV and in near-central C+C and Si+Si reactions at 158A GeV are presented. Transverse mass spectra, rapidity ...
Energy dependence of particle ratio fluctuations in central Pb+Pb collisions from [sqrt s [subscript NN]]=6.3 to 17.3 GeV
(American Physical Society, 2009-04)
We present measurements of the energy dependence of event-by-event fluctuations in the K/pi and (p+p[over-bar])/pi multiplicity ratios in heavy-ion collisions at the CERN SPS. The particle ratio fluctuations were obtained ...
System Size, Energy, and Centrality Dependence of Pseudorapidity Distributions of Charged Particles in Relativistic Heavy-Ion Collisions
(American Physical Society, 2008-04)
We present the first measurements of the pseudorapidity distribution of primary charged particles in Cu+Cu collisions as a function of collision centrality and energy, [sqrt]s[subscript NN]=22.4, 62.4, and 200 GeV, over a ...
