Abstract
Inclusive jet and dijet cross-sections are measured in proton-proton collisions at a centre-of-mass energy of 13TeV. The measurement uses a dataset with an integrated luminosity of 3.2 fb1 recorded in 2015 with the ATLAS detector at the Large Hadron Collider. Jets are identied using the anti-kt algorithm with a radius parameter value of R = 0:4. The inclusive jet cross-sections are measured double-dierentially as a function of the jet transverse momentum, covering the range from 100 GeV to 3.5TeV, and the absolute jet rapidity up to jyj = 3. The double-dierential dijet production cross-sections are presented as a function of the dijet mass, covering the range from 300 GeV to 9TeV, and the half absolute rapidity separation between the two leading jets within jyj < 3, y, up to y = 3. 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 eects are compared to the measured cross-sections.| File | Dimensione | Formato | |
