First measurement of hadronic event shapes in pp collisions at root s=7 TeV

Abstrakt

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.
