Abstract
In this study, we aim to study jet production in the central regions (|η| < 2.5) and the forward regions (3 < |η| < 5) in a proton-proton collision at different energies: √s = 13.6 TeV, √s = 20 TeV and at √s = 27 TeV. In addition, the measurement of dijets where the dijets selected one is the leading central jet and the second jet is the sub-leading forward jet was investigated at the same collision energies. Jets are reconstructed with the anti-KT algorithm (R= 0.5) in the transverse momentum range pT = 15-1000 GeV/c. Different Monte Carlo event generators were used: PYTHIA, HERWIG, and EPOS-LHC.It was observed that the jets and dijets multiplicities increase as the energy of the collision increases. Furthermore, it was observed that the jet multiplicity at central regions is larger than the forward regions with the three energies. Also, a little disagreement between different generators of some data was noticed. The possible reason for this is that each event generator depends on a different theoretical model. This study of the forward and the central jets at future energies anticipated by LHC could help to offer insightful information about the characteristics of these jets and their implications for future research physics.
