Abstract
Quantum Chromodynamics (QCD) measurements represent an extensive part of the early physics program of the ATLAS experiment at LHC. In this contribution a selection of the first ATLAS QCD measurements is presented. The results are based on a part of the data sets collected during 2010 at the centre of mass energy of √s = 7TeV. The contribution includes an overview of the underlying event studies. A large number of measurements involving jets is also illustrated. After the investigation of jet shapes, the measurements of the cross section of the inclusive, dijet, multi-jet and bosons plus jets processes are presented. The angular decorrelations results in dijet events are also discussed. Finally the measurement of the prompt photon cross section is shown. The measurements are compared to the predictions from different Monte Carlo (MC) generators implementing leading-order (LO) matrix elements supplemented by parton showers, and to next-to-leading order (NLO) perturbative QCD (pQCD) calculations.
