Title: Multiplicity predictions for Pb-Pb collisions at \(\sqrt{s} = 5.02\) TeV based on the MC Modified Glauber model Author:Seryakov, Andrey; Feofilov, Grigory Contributor:Feofilov, Grigory (pacrepositoryorg) Subject:Collisions ; Mathematical Models ; Monte Carlo Method ; Predictions ; Computer Simulation ; Energy Conservation Description:
We present predictions of the mean multiplicity yields for different centrality classes of Pb-Pb collisions at \(\sqrt{s} = 5.02\) TeV at the LHC, obtained using the Monte-Carlo Modified Glauber model (MGM) [1]. Contrary to generally used standard Glauber calculations, the MGM takes into account the energy conservation in the soft particles production. The only one efficient model parameter was tuned and fixed previously (k=0.35) by fitting the available data on multiplicity for all colliding systems up to RHIC energies. The MGM has shown already a good predictive capability for the yields at \(\sqrt{s} = 2.76\) TeV, and it is used again within the same MC code for the calculations at \(\sqrt{s} = 5.02\) TeV

Title: Constraints on string percolation model from anomalous centrality evolution data in Au-Au collisions at \(\mathbf{\sqrt{s_{NN}}=}\) 62 and 200 GeV Author:Feofilov, Grigory; Altsybeev, Igor; Kochebina, Olga Contributor:Kochebina, Olga (pacrepositoryorg) Subject:Qualitative Analysis ; Collisions ; Evolution ; Flux Density ; Constraint Modelling ; Percolation ; Strings ; Computer Simulation Description:
Anomalous centrality evolution of two-particle angular correlations observed in Au-Au collisions at \(\sqrt{s_{NN}} = 62\) and 200 GeV and the onset of ridge structures are considered in the model of interacting quark-gluon strings. We assume that at the given energy of nucleus-nucleus collisions the critical energy density may be reached at the specific centrality. In a string percolation model this might be treated equivalently to a formation of a large cluster of strings characterized by the critical string density, with a size comparable to the whole area of interaction of two nuclei. This hypothesis allows to define some constraints on the string percolation model using data on transitional centralities in Au-Au collisions at these two energies. Results are extrapolated to the LHC energy where high string densities (exceeding the critical value) are confirmed for all classes of centralities in Pb-Pb collisions. Interaction between strings inside large clusters formed in nucleus-nucleus...

Anomalous centrality evolution of two-particle angular correlations observed in Au-Au collisions at $\sqrt{s_{NN}} = 62$ and 200 GeV and the onset of ridge structures are considered in the model of interacting quark-gluon strings. We assume that at the given energy of nucleus-nucleus collisions the critical energy density may be reached at the specific centrality. In a string percolation model this might be treated equivalently to a formation of a large cluster of strings characterized by the critical string density, with a size comparable to the whole area of interaction of two nuclei. This hypothesis allows to define some constraints on the string percolation model using data on transitional centralities in Au-Au collisions at these two energies. Results are extrapolated to the LHC energy where high string densities (exceeding the critical value) are confirmed for all classes of centralities in Pb-Pb collisions. Interaction between strings inside large clusters formed in nucleus-nucleus collisions is considered in a simplified Monte Carlo model. This model is applied to the qualitative analysis of the onset of collectivity and the ridge formation in Pb-Pb collisions. It is shown that the approach of the repulsive string-string interaction is capable to explain the appearance of elliptic and triangular flow observed in nucleus-nucleus collisions at RHIC and LHC energies.
