Nuclear collisions between hadron-hadron and nucleus-nucleus at relativistic energies give
good chance to study the properties of nuclear matter in terms of partonic processes. Now
many of experimental data are available with a wide range of energies starting from center
of mass (cm) energy√= 0.9 TeV, via 2.36 TeV, to the current maximum energy of 7 TeV [1–
5]. In addition to the projectile energies, the mass number of interacting heavy nuclei such as
Pb+ Pb and Au+ Au, increases the possibility for the number of interacting nucleons ...
