Abstract

Jets in high energy hadron-hadron collisions emerge from the interaction of partons at high transverse momenta p_T. The dynamic of hadron jets in proton-proton collisions provides essential information about Parton scattering. The studying of very forward dijet events is very important to enhance the sensitivity to very small-x Parton dynamics. Azimuthal angle decorrelation is a sensitive probe for details of QCD radiation in hard parton scattering. A study of azimuthal angle decorrelations of Mueller-Navelet and inclusive dijet cross-section in proton-proton collisions were performed for jets with pT>5 GeV and different values of pseudorapidity ∆η using different Monte Carlo generators samples at √s = 13 TeV. This work using various Monte-Carlo generators to make a Comparison that allows distinguishing among various Monte-Carlo generators and their tunes. Monte Carlo generator samples used are Pythia8 CUETP8M1, Pythia8 MBR and EPOS-LHC. For each value of pseudorapidity ∆η, the dijet cross-section and ∆φ distributions for MN dijets are measured.
