Abstract
Dynamical charge fluctuations have been studied in ultrarelativistic heavy-ion collisions by using hadronic model simulations, such as Ultrarelativistic Quantum Molecular Dynamics (UrQMD) and Heavy Ion Jet Interaction Generator (HIJING). The evolution of fluctuations has been calculated at different time steps during the collision as well as at different observation windows in pseudorapidity . The final state effects on the fluctuations have been investigated by varying and the time steps with the aim of obtaining an optimum observation window for capturing maximum fluctuations. It is found that between 2.0 and 3.5 gives the best coverage for the fluctuations studies. The results of these model calculations for collisions at = 7.7 to 200 GeV and for collisions at 2.76 TeV are presented and compared to the available experimental data from the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC).
