Inclusive jet production cross-sections are measured in proton-proton collisionsat a centre-of-mass energy of √s = 8 TeV recorded by the ATLAS experiment at theLarge Hadron Collider at CERN. The total integrated luminosity of the analysed data setamounts to 20.2 fb−1. Double-differential cross-sections are measured for jets defined bythe anti-kt jet clustering algorithm with radius parameters of R = 0.4 and R = 0.6 andare presented as a function of the jet transverse momentum, in the range between 70 GeVand 2.5 TeV and in six bins of the absolute jet rapidity, between 0 and 3.0. The measuredcross-sections are compared to predictions of quantum chromodynamics, calculatedat next-to-leading order in perturbation theory, and corrected for non-perturbative andelectroweak effects. The level of agreement with predictions, using a selection of differentparton distribution functions for the proton, is quantified. Tensions between the data andthe theory predictions are observed.
