Measurement of inclusive jet and dijet cross-sections in proton-proton collisions at $\sqrt{s}=13$ TeV with the ATLAS detector

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