Generalized effective string rope model for the initial stages of ultrarelativistic heavy ion collisions
We present a generalized effective string rope model (GESRM), which aims to describe the initial stage of relativistic heavy ion collisions and to give us an initial state for further hydrodynamical calculations. We start with the effective string rope model (ESRM) [V. K. Magas, L. P. Csernai, and D...

| Sumario: | We present a generalized effective string rope model (GESRM), which aims to describe the initial stage of relativistic heavy ion collisions and to give us an initial state for further hydrodynamical calculations. We start with the effective string rope model (ESRM) [V. K. Magas, L. P. Csernai, and D. D. Strottman, Phys. Rev. C 64, 014901 (2001); Nucl. Phys. A 712, 167 (2002)] and generalize it in order to take into account fluctuations in the initial state following the Glauber Monte Carlo approach. Results from symmetric nucleus-nucleus collisions at different impact parameters are presented at energies available at the BNL Relativistic Heavy Ion Collider (RHIC) and the CERN Large Hadron Collider (LHC); additionally we study asymmetric A+Au head-on collisions. We also compare the results obtained in the GESRM on an event-by-event basis with those received averaging initial states over many events |
