PACIAE Model Predictions for Pb+Pb Collisions at LHC Compared to the Au+Au Collisions at RHIC
Abstract
The parton and hadron cascade model PACIAE is used to simulate the 0-6, 15-25, and 35-45 % most central Au+Au collisions at sNN=19.6, 62.4, 130, and 200 GeV and the 0-10 % most central Pb+Pb collisions at sNN=5500 GeV. The calculated charged multiplicity and the charged particle transverse momentum distribution, pseudorapidity distribution, and extended longitudinal scaling for Au+Au collisions well agree with the corresponding PHOBOS data. Thus the above observables calculated for Pb+Pb collisions would be a reliable prediction.
