Nucleon shadowing effects in $Cu+Cu$ and $Au+Au$ collisions at RHIC within the HIJING code

Khaled Abdel-Waged, Nuha Felemban

The centrality dependence of pseudorapidity density of charged particles ($d{N}_{ch}/d\eta$) in $Cu+Cu$ ($Au+Au$) collisions at RHIC energy of $\sqrt{s_{{}_{\mathrm{NN}}}}=22.4$ , $62.4$ an…
