Elucidating the jet cross-section in p p and p P b collisions at √s N N = 5.02 TeV

In this paper, we present the charged particles jet cross-section study in pp and pPb collisions at sNN = 5.02,TeV using PYTHIA8 (PYTHIA8.186 and PYTHIA8.306) and HIJING 2.0 models, in kinematic range of 5 < pT < 100,GeV/c for pp collisions and 20 < pT < 120,GeV/c for pPb collisions. The jets are reconstructed for R = 0.2, 0.3, 0.4 and 0.6 for the pseudorapidity interval of |η| < 0.9-R. The jets algorithms: cell jet and slow jet inside PYTHIA8.186 and anti-kT algorithm using HIJING 2.0 have been used for Monte Carlo simulations. The simulation results are then compared with measurements of the ALICE experiment. It is observed that all models' predictions are lower than experimental data up to pT = 20,GeV/c; after that, the Monte Carlo study of Cell and slow jet satisfies the experimental data. The CR tunes could not explain the ALICE data at high pT values due to nonperturbative QCD effects. We have also calculated the nuclear modification factor RpPb, and no clear suppression has been seen in the case of pPb collisions. The results from the models indicate that the QGP is not formed and that the cold nuclear matter effect exists in pPb collisions.
