Dijet Angular Distributions in Proton-Proton Collisions

The textbook "Dijet Angular Distributions in Proton-Proton Collisions" by Nele Boelaert provides a comprehensive analysis of the first data collected at the Large Hadron Collider (LHC) at CERN. The work addresses the measurement of scattering angles in the search for new physical phenomena and subatomic structures. By examining the collisions of quarks and gluons, which emerge as directed particle streams or jets from the proton collisions, a classic Rutherford scattering experiment is adapted to modern conditions. The dissertation includes a phenomenological study at the design energy of the LHC of 14 TeV and utilizes a model of so-called large extra dimensions as a reference process to assess sensitivity to new physical entities. The experimental results captured by ATLAS in 2010 at a starting energy of 7 TeV are compatible with the Standard Model and demonstrate an understanding of the physics and the apparatus used. This work lays the foundation for future measurements as the LHC continues to collect data and increase its energy.
