Mueller-Navelet jets in high-energy hadron collisions

Abstract

We consider within QCD collinear factorization the process $p+p\to \mathrm{jet}+\mathrm{jet}+X$, where two forward high-$p_T$ jets are produced with a large separation in rapidity $\Delta y$ (Mueller-Navelet jets [1]). The hard part of the reaction receives large higher-order corrections $\sim {\alpha }_s^n(\Delta y{)}^n$, which can be accounted for in the BFKL approach. We calculate cross section and azimuthal decorrelation, using the next-to-leading order jet vertices, in the small-cone approximation [2].
