Özet

Higher collision energies at future colliders may eventually lead to the falsification of standard fixed-order perturbation theory and linear evolutions due to nonlinear structure of QCD at small-x. New physics research works that are strictly based on accurate jet measurements will undoubtedly have this observation known as Balitsky-Fadin-Kuraev-Lipatov (BFKL) effect via angular jet decorrelations taking into account the Mueller-Navelet jets. As one of the frontier colliders, FCC-ep, has a great observation potential on parton densities through asymmetrical collisions. We aim to test the observability of azimuthal angular jet decorrelations with the recent event generators (HERWIG, PYTHIA) at the generator and detector level for FCC-ep center of mass energies s=3.5TeV in proton-electron collisions. Jets are reconstructed by the anti-kT algorithm (R=0.5), with pT>15GeV and selected in the range of |<6. Relevant pseudo-rapidity regions have been analyzed with the azimuthal-angle difference between Mueller-Navelet Jets (Δφ) in the pseudo-rapidity separation (Δη) and the distributions of (cos(n(π-Δφ))) are presented in comparison as the result.
