Ratios of angular moments as functions of rapidity gap.

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 \sqrt{s} = 100 TeV with proton-proton collisions and jets, that are reconstructed by the Anti-k_{T} algorithm (R=0.7), with p_{T}>35GeV and in the rapidity range of |y|<6 are selected for the study. The azimuthal-angle difference between Mueller-Navelet Jets (\Delta\text{{\Phi}} ) in the rapidity seperation (\Delta y) up to 12 is analysed. The distributions of <cosn(\pi-\Delta\Phi)> for n=1,2,3 and their ratio are also presented as a function of \Delta y.
