Abstract

New event generator configurations for the modelling of jet production at √s = 13 TeV with the ATLAS detector are presented. Monte Carlo samples were obtained using the Pythia 8.230, Madgraph + Pythia 8.212, Herwig 7.1.3, Powheg + Pythia 8.230 and Sherpa 2.2.5 generators. The predictions of the different generators are compared to a measurement of the inclusive jet spectrum at √s = 13 TeV and to each other in distributions of global event observables and jet substructure variables. Prescriptions to evaluate uncertainties in the perturbative and non-perturbative parts of these computations are discussed, and their impact is evaluated on selected distributions.
