【 摘 要 】

Hadronic event shapes have been measured in proton–proton collisions at √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.
