Abstract:
The azimuthal angular decorrelation that is relevant to small-x QCD physics is studied in this paper to show the BFKL effect with a recent event generator. Events are generated at root s = 100 TeV with proton- proton collisions and jets that are reconstructed by the anti-k(T) algorithm (R = 0.7) with p(T) > 35 GeV and in the rapidity range of vertical bar y vertical bar < 6 are selected for the study. The azimuthal-angle difference between Mueller-Navelet jets (Delta Phi) in the rapidity separation (Delta y) up to 12 is analysed. The distributions of < cos n(pi-Delta Phi)> for n = 1, 2, 3 and their ratios are also presented as a function of Delta y.
