Global characteristics of nucleus-nucleus collisions in an ultrarelativistic domain / Savina, M V ; Shmatov, S V ; Slavin, N V ; Zarubin, P I
The global observable distributions of nucleus-nucleus collisions at a high energy are studied. It is shown that these distributions are sensitive to interaction dynamics and can be used to investigate the evolution of dense nuclear matter [...]

Particle rapidity density and collective phenomena in heavy ion collisions / Ugoccioni, R (Lisbon, IST) ; Dias de Deus, J (Lisbon, IST)
We analyse recent results on charged particle pseudo-rapidity densities from RHIC in the framework of the Dual String Model, in particular when including string fusion. The model, in a simple way, agrees with all the existing data and is consistent with the presence of the percolation transition to the Quark-Gluon Plasma already at the CERN-SPS. [...]

Photon emission in Pb + Pb collisions at SPS and LHC / Peressounko, D Yu ; Pokrovsky, Yu E
Yield of direct photons in Pb+Pb collisions at SpS and LHC energy is evaluated with emphasis on estimate of possible uncertainty. Possibility of experimental observation of direct photons at LHC is discussed. [...]

Status and prospects of the CERN-LHC experiment ALICE / Schmidt, H R /ALICE Collaboration
An overview of the prevailing experimental conditions at the CERN-LHC for heavy-ion collisions is given. Observables, in particular those unique to the LHC energy regime, are discussed. [...]

The improved nuclear parton distributions / Filho, A L A ; Gonçalves, V P
In this paper we propose an improvement of the EKS nuclear parton distributions for the small x region of high energy processes, where the perturbative high parton density effects cannot be disregarded. We analyze the behavior of the ratios $xG_A/xG_N$ and $F_2^A/F_2^D$ and verify that at small x they are strongly modified when compared to the EKS predictions. [...]

A Dynamical Scaling Law for Jet Tomography / Salgado, Carlos A. (CERN) ; Wiedemann, Urs Achim (CERN)
Medium modifications of parton fragmentation provide a novel tomographic tool for the study of the hot and dense matter created in ultrarelativistic nucleus-nucleus collisions. Their quantitative analysis, however, is complicated by the strong dynamical expansion of the collision region. [...]

Strong nuclear enhancement in intermediate mass Drell-Yan production / Jian Wei Qiu ; Xiao Fei Zhang
We calculate nuclear effect in Drell-Yan massive lepton-pair production in terms of parton multiple scattering in Quantum Chromodynamics (QCD). We present the nuclear modification to inclusive Drell-Yan cross sections d sigma /dQ/sup 2/ in terms of multiparton correlation functions. [...]

Suppression of quarkonium production in heavy-ion collisions at RHIC and LHC / Gerland, L ; Frankfurt, L L ; Strikman, M I ; Stöcker, H ; Greiner, W
A model for the production of quarkonium states in the mid-rapidity region at the RHIC and LHC energy range is presented which explores well understood properties of quantum chromodynamics only. An increase of the quarkonium hadronization time with the initial energy leads to a gradual change of the most important phenomena from fixed target to collider energies. [...]

Particle production and equilibration in heavy ion collisions / Redlich, Krzysztof ; Cleymans, J ; Oeschler, H ; Tounsi, A
The application of statistical model in heavy ion collisions is discussed in the energy range from SIS/GSI through AGS/BNL up to SPS /CERN and RHIC/BNL. It is shown that in this broad energy range hadronic yields and their ratios resemble a thermal equilibrium population along a unified freeze-out curve determined by the condition of fixed energy per particle approximately= 1 GeV.

A signature for the formation of the quark-gluon plasma in nucleus-nucleus collisions / He Ze Jun ; Jiang Wei, Z ; Zhuang, B ; Liu, B ; Zhang Jia Ju
Based on thermodynamic relations, the initial values of the quark- gluon system from relativistic nucleus-nucleus collisions are obtained. Using these initial values we have studied the dilepton production on the basis of the relativistic hydrodynamic model, and found that with increasing incident energy a characteristic plateau indicating the formation of the quark-gluon plasma appears in the total yield, which may be tested in future experiments in CERN and Brookhaven.
