Measurement of multijet events with ATLAS

The production of jets at hadron provides stringent tests of perturbative QCD. We present the latest measurements using proton-proton collision data collected by the ATLAS experiment at sqrt(s)=13 TeV. We will discuss the measurement of new event-shape jet observables defined in terms of reference geometries with cylindrical and circular symmetries using the Energy Mover's Distance. The results are unfolded for detector effects and compared to the state-of- the-art next-to-leading order parton shower generators.
