Centrality Dependence of the Charged-Particle Multiplicity Density at Midrapidity
Quantum chromodynamics (QCD), the theory of the strong interaction, predicts a phase transition at high temperature between hadronic and deconfined matter (the quark-gluon plasma). Strongly interacting matter under such extreme conditions can be studied experimentally using ultrarelativistic collisions of heavy nuclei. The field entered a new era in November 2010 when the Large Hadron Collider ...
متن کاملCentrality dependence of the multiplicity and transverse momentum distributions at RHIC and LHC and the percolation of strings
The dependence of the multiplicity and the transverse momentum distribution on the number of collisions are studied for central and peripheral Au-Au collisions at SPS, RHIC and LHC energies in the framework of percolation of strings. A scaling law relating the multiplicity to the mean transverse momentum is obtained. Our results are in overall agreement with the SPS and RHIC data, obtaining a s...
متن کاملEnergy dependence of transverse particle production from SPS to RHIC
Transverse momentum spectra up to 4.5GeV/c were measured around midrapidity in Pb+Pb collisions at √ sNN = 17.3GeV, for π±, p, p̄ and K±, by the NA49 experiment. The nuclear modification factors RAA, RAA/pA and RCP were extracted and are compared to RHIC results at √ sNN = 200GeV. The modification factor RAA shows a rapid increase with transverse momentum in the covered region. The modification ...
متن کاملCharge Particle Multiplicity and Transverse Energy Measurements in Au-Au collisions in PHENIX at RHIC
We present results on charged particle (dNch/dη) and transverse energy densities (dET/dη) measured at mid-rapidity in Au-Au collisions at √ s NN =200 GeV. The mean transverse energy per charged particle is derived. The results are presented as a function of centrality, which is defined by the number of participating nucleons (Np), and compared to results obtained in Au-Au collisions at √ s NN =...
متن کاملTransverse Energy Production at Rhic
The Relativistic Heavy Ion Collider (RHIC) will provide us with a unique opportunity to study matter under extreme conditions. The transition from hadronic degrees of freedom to quark and gluon degrees of freedom is expected from collisions at these energies. The transverse energy spectrum will be among the very first results from RHIC. One important question we would like to answer from the da...
