Search for Quark Compositeness in 7 TeV Proton-Proton Collisions with the ATLAS Detector at the Large Hadron Collider

description Quarks and leptons are assumed to be fundamental particles in the Standard Model of particle physics. The Large Hadron Collider provided 7 TeV proton-proton collisions in 2010. These collisions permit the search for quark substructure at a smaller length scale than was previously possible. This thesis is an investigation of the angular distribution of high dijet mass events in 36 pb^{−1} of data recorded by the ATLAS detector. Further contributions to technical aspects of the analysis are described in the appendices. This analysis excludes quark substructure at Λ < 5.3 TeV, corresponding to 3.7 × 10^{−5} fm, at 95% confidence level.
