The size of the sample corresponds to an integrated luminosity of~78\,nb${}^{-1}$. Jets constructed with different techniques are used as input for calculating event-shape variables, which probe the structure of the hadronic final state. Normalized event-shape distributions are shown to be robust against various sources of systematic uncertainty. It is demonstrated that these early measurements of event-shape variables are sensitive to differences in the modeling of QCD multi-jet production.
