Jets in High Energy Hadronic Collisions

The jet production in proton-proton, proton-nucleus and nucleus-nucleus collisions at relativistic and ultrarelativistic energies using the HIJING is studied and discussed. We analyzed the distributions of multiplicity of secondary charged particles, their pseudorapidity, rapidity and the transverse mass as a function of the number of jets. These parameters are used to estimate energy density and temperature of the hadronic matter to get the signal about QGP formation. For ultrarelativistic energy we considered pp at 14 TeV, PbPb at 5.5 TeV, pPb at 8.8 TeV and ArAr at 6.3 TeV, same as in ALICE and also at 25.0 GeV as relativistic energy. We obtained some insights about some properties of jets and their influences on the characteristics of the secondary particles produced in relativistic and ultrarelativistic hadronic collisions. In this text the background information about the jet production is presented in chapter 1. Chapter 2 contains description of the HIJING parameters. Chapter 3 is a description of the ALICE detectors. The results obtained by using the HIJING for pp, pA and AA interactions are presented and discussed in Chapter 4. Chapter 5 summarizes the conclusions.
