- Study of hadronic event-shape variables in multijet final states in pp collisions at sqrt(s) = 7 TeVPublication . CMS collaboration (2135 authors); Hollar, Jonathan; Nayak, Aruna; Bargassa, Pedrame; Beirão Da Cruz E Silva, Cristóvão; Faccioli, Pietro; Ferreira Parracho, Pedro Guilherme; Gallinaro, Michele; Nguyen, Federico; Rodrigues Antunes, Joao; Seixas, Joao; Varela, Joao; Vischia, Pietro; Lloret Iglesias, Lara; David Tinoco Mendes, Andre; Musella, Pasquale; Silva, Pedro; Pela, Joao; Leonardo, NunoEvent-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.
