Charged-particle pseudorapidity distributions in Au+Au collisions at RHIC

  • Using the Glauber model, we present the formulas for calculating the numbers of participants, spectators and binary nucleon-nucleon collisions. Based on this work, we get the pseudorapidity distributions of charged particles as the function of the impact parameter in nucleus-nucleus collisions. The theoretical results agree well with the experimental observations made by the BRAHMS Collaboration in Au+Au collisions at √sNN=200 GeV in different centrality bins over the whole pseudorapidity range.

Charged-particle pseudorapidity distributions in Au+Au collisions at RHIC

    Corresponding author: JIANG Zhi-Jin,

Abstract: 

Using the Glauber model, we present the formulas for calculating the numbers of participants, spectators and binary nucleon-nucleon collisions. Based on this work, we get the pseudorapidity distributions of charged particles as the function of the impact parameter in nucleus-nucleus collisions. The theoretical results agree well with the experimental observations made by the BRAHMS Collaboration in Au+Au collisions at √sNN=200 GeV in different centrality bins over the whole pseudorapidity range.
