Search for quark contact interactions in dijet angular distributions in pp collisions at √s=7 TeV measured with the ATLAS detector

Abstract

Dijet angular distributions from the first LHC pp collisions at center-of-mass energy √s=7 TeV have been measured with the ATLAS detector. The dataset used for this analysis represents an integrated luminosity of 3.1 pb^(−1). Dijet χ distributions and centrality ratios have been measured up to dijet masses of 2.8 TeV, and found to be in good agreement with Standard Model predictions. Analysis of the χ distributions excludes quark contact interactions with a compositeness scale Λ below 3.4 TeV, at 95% confidence level, significantly exceeding previous limits.

We are profoundly grateful to everyone at CERN involved in operating the LHC in such a superb way during this initial high energy data-taking period. We acknowledge equally warmly all the technical and administrative staff in the collaborating institutions without whom ATLAS could not be operated so efficiently.
