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 root s = 3:5 TeV in proton-electron collisions. Jets are reconstructed by the anti-kT algorithm (R = 0:5), with p(T) > 15 GeV and selected in the range of vertical bar eta vertical bar< 6. Relevant pseudo-rapidity regions have been analyzed with the azimuthal-angle di (R) erence between Mueller{Navelet Jets (Delta phi) in the pseudo-rapidity separation (Delta eta) and the distributions of < cos(n(pi-Delta phi >>> are presented in comparison as the result.
