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-$k_{\mathrm{T}}$ algorithm ($R=0.7$) with $p_{\mathrm{T}}>35$ GeV and in the rapidity range of $|y|<6$ are selected for the study. The azimuthal-angle difference between Mueller--Navelet jets ($\Delta{\mit\Phi}$) in the rapidity separation ($\Delta y$) up to $12$ is analysed. The distributions of $\langle\cos n(\pi-\Delta{\mit\Phi})\rangle$ for $n=1,2,3$ and their ratios are also presented as a function of $\Delta y$.
