Δ-scaling and information entropy in ultra-relativistic nucleus-nucleus collisions

The Delta-scaling method has been applied to ultra-relativistic p+p, C+C and Pb+Pb collision data simulated using a high-energy Monte Carlo package, LUCIAE 3.0. The Delta-scaling is found to be valid for some physical variables, such as charged particle multiplicity, strange particle multiplicity and number of binary nucleon-nucleon collisions from these simulated nucleus-nucleus collisions over an extended energy ranging from E-lab = 20 to 200A GeV. In addition we derive the information entropy from the multiplicity distribution as a function of beam energy for these collisions.
