Abstract

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 √s = 7TeV. Events are selected with at least one jet with transverse momentum pT > 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 pT ranges are compared to predictions from different QCD Monte Carlo event generators.
