Measurement of Inclusive Jet and Dijet Cross-Sections in Proton–proton Collisions at √S = 13 TeV With the ATLAS Detector

Abstract

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 with an integrated luminosity of 3.2 fb−1 recorded in 2015 with the ATLAS detector at the Large Hadron Collider. Jets are identified using the anti-kt 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 mo- mentum, covering the range from 100 GeV to 3.5 TeV, and the absolute jet rapidity up to |y| = 3. The double-differential dijet production cross-sections are presented as a function of the dijet mass, covering the range from 300 GeV to 9 TeV, and the half absolute rapidity sep- aration between the two leading jets within |y| < 3, y∗, up to y∗ = 3. Next-to-leading-order, and next-to-next-to-leading-order for the inclusive jet measurement, perturbative QCD calcu- lations corrected for non-perturbative and electroweak effects are compared to the measured cross-sections.
