Studies of jet cross-sections and production properties with the ATLAS and CMS detectors

Several characteristics of jet production in pp collisions have been measured by the ATLAS and CMS collaborations at the LHC. Measurements of event shapes and multi-jet production probe the dynamics of QCD in the soft regime and can constrain par ton shower and hadronisation models. Measurements of multi jet systems with a veto on additional jets probe QCD radiation effects. Double-differential cross-sections for three and four jetfinal states are measured at different centre-of-mass energies of pp collisions and are compared to expectations based on NLO QCD calculations. The distribution of the jet charge has been measured in di-jet events and compared to predictions from different hadronisation models and tunes. Jet-jet energy correlations are sensitive to the strong coupling constant. These measurements constitute precision tests of QCD in a new energy regime.
