Study of Hadronic Event-Shape Variables in Multijet Final States in pp Collisions at $\sqrt{s}$ = 7 TeV

Event-shape variables, which are sensitive to perturbative and nonperturbative aspects of quantum chromodynamic (QCD) interactions, are studied in multijet events recorded in proton-proton collisions at $\sqrt{s} = 7$ TeV. Events are selected with at least one jet with transverse momentum p$_{T}$ > 110 GeV and pseudorapidity |η| < 2.4, in a data sample corresponding to integrated luminosities of up to 5 fb$^{−1}$. The distributions of five event-shape variables in various leading jet p$_{T}$ ranges are compared to predictions from different QCD Monte Carlo event generators.
