The triple differential di-jet cross section at the LHC

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 com...

description 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.
