Study of hadronic event-shape variables in multijet final states in pp collisions at TeV
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 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. [Figure not available: see fulltext.]
