Resumo
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 root s = 7 TeV. Events are selected with at least one jet with transverse momentum p(T) > 110 GeV and pseudorapidity vertical bar eta vertical bar < 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.
