Abstract

The measurement of the triple-differential dijet production cross section as a function of the average
transverse momentum pT;avg, half the rapidity separation y, and the boost yb of the two leading jets in the
event enables a kinematical scan of the underlying parton momentum distributions. We compute for the
first time the second-order perturbative QCD corrections to this triple-differential dijet cross section, at
leading color in all partonic channels, thereby enabling precision studies with LHC dijet data. A detailed
comparison with experimental CMS 8 TeV data is performed, demonstrating how the shape of this
differential cross section probes the parton densities in different kinematical ranges.
