 Inclusive jet and dijet cross-sections are measured in proton-proton collisions<br />at a centre-of-mass energy of 13 TeV. The measurement uses a dataset with an integrated<br />luminosity of 3.2 fb−1<br />recorded in 2015 with the ATLAS detector at the Large Hadron<br />Collider. Jets are identified using the anti-kt algorithm with a radius parameter value of<br />R = 0.4. The inclusive jet cross-sections are measured double-differentially as a function<br />of the jet transverse momentum, covering the range from 100 GeV to 3.5 TeV, and the absolute<br />jet rapidity up to |y| = 3. The double-differential dijet production cross-sections are<br />presented as a function of the dijet mass, covering the range from 300 GeV to 9 TeV, and<br />the half absolute rapidity separation between the two leading jets within |y| < 3, y∗, up to<br />y∗ = 3. Next-to-leading-order, and next-to-next-to-leading-order for the inclusive jet measurement,<br />perturbative QCD calculations corrected for non-perturbative and electroweak effects are compared to the measured cross-sections.
