NNLO QCD predictions for single jet inclusive production at the LHC

Abstract

We report the first calculation of fully differential jet production in all partonic channels at next-to-next-to leading order (NNLO) in perturbative QCD and compare to the available ATLAS 7 TeV data. We discuss the size and shape of the perturbative corrections along with their associated scale variation across a wide range in jet transverse momentum, $p_T$, and rapidity, $y$. We find significant effects, especially at low $p_T$, and discuss the possible implications for Parton Distribution Function fits.
