Azimuthal Angular Decorrelation of Jets at Future High Energy Colliders

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| for n=1,2,3 and their ratio are also presented as a function of \Delta y.
