Abstract

Hadronic event shapes have been measured in proton-proton collisions at root s = 7 TeV, with a data sample collected with the CMS detector at the LHC. The sample corresponds to an integrated luminosity of 3.2 pb(-1). Event-shape distributions, corrected for detector response, are compared with five models of QCD multijet production. (C) 2011 CERN.
