Studies of jet production properties and the strong coupling constant with the ATLAS detector

Several aspects of jet production in proton-proton collisions have been measured by the ATLAS Collaboration. The measurements of the jet production cross sections probe the dynamics of QCD and can constrain the parton proton structure. Cross-sections for inclusive jet, three-jet and four-jet final states are measured differentially in a variety of kinematic variables and for different centre-of-mass energies in proton-proton collisions with the ATLAS detector. Experimental results are compared to expectations based on next-to-leading order QCD calculations as well as to the Monte Carlo simulations. First LHC Run-2 results are also presented. The measurement of the jet-jet transverse energy correlations sensitive to the strong coupling constant is discussed. The momentum-weighted sum of the charges of tracks associated to a jet is sensitive to the electrical charge of the parton initiating the jet. The distribution of the so-called jet charge has been measured in dijet events using proton-proton collision data.
