We argue that string percolation is in the origin of i) an approximately flat rapidity distribution and of ii) an approximately constant forward-backward correlation parameter b over a substantial fraction of the available rapidity. Predictions are given for pp collisions at LHC, √ s = 14TeV and √ s = 5.5TeV. Key words:Long range rapiditiy correlations, LHC, Percolation, Particle densities, Proton collisions PACS: 25.75. Nq, 12.38.Mh, 24.85.+p In AA (nucleus-nucleus or hadron-hadron) high energy collisions one naturally expects positive Forward-Backward (F-B) correlations to occur. This happens because the overlap area of interaction acts both in the forward and in the backward direction. If the impact parameter is small, many particles are emitted forward, and many particles are emitted backward. On the

“…. (see [13] for a study of evolution of particle and energy densities). Nevertheless, it is usually assumed that the enhancement of hyperons, antihyperons and φ's observed in heavy ion experiments at SPS [4,5,6,7,8] cannot be fully explained by using exclusively a mechanism which goes beyond the independent string hypothesis, as string fusion [12,16,17,18,39] or baryon junction migration [18,28,49,50,51].…”

“…In this paper a non-QGP model for collisions between nucleons or nuclei in the energy range going from SPS energies (∼ 20 GeV per nucleon in the center of mass) to LHC energies (5.5 TeV per nucleon in the center of mass) is presented (different steps in this direction can be found in [12,13]). The model is based on the ideas of Dual Parton Model (DPM) [14] or Quark-Gluon String Model (QGSM) [15], considering both soft and semihard components on a partonic level.…”

A Monte Carlo model to simulate nuclear collisions in the energy range going from SPS to LHC, is presented. The model includes in its initial stage both soft and semihard components, which lead to the formation of color strings. Collectivity is taken into account considering the possibility of strings in color representations higher than triplet or antitriplet, by means of string fusion. String breaking leads to the production of secondaries. At this point, the model can be used as initial condition for further evolution by a transport model. In order to tune the parameters and see the results in nucleus-nucleus collisions, a naif model for rescattering of secondaries is introduced. Results of the model are compared with experimental data, and predictions for RHIC and LHC are shown.

Can shadowing mimic the QCD phase transition?

The directed flow of protons is studied in the quark-gluon string model as a function of the impact parameter for S+S and Pb+Pb reactions at 160 AGeV/c. A significant reduction of the directed flow in midrapidity range, which can lead to the development of the antiflow, is found due to the absorption of early emitted particles by massive spectators (shadowing effect). This effect can mimic the formation of the quark-gluon plasma (QGP). However, in the absorption scenario the antiflow is stronger for the system of light colliding nuclei than for the heavy ones, while in the case of the plasma creation the effect should be opposite.Comment: REVTEX, 11 pages, 5 figures embedded, accepted for publication in Physics Letters
