This book describes research in two different areas of state-of-the-art hadron collider physics, both of which are of central importance in the field of particle physics. The first part of the book focuses on the search for supersymmetric particles called gluinos. The book subsequently presents a set of precision measurements of multi-jet collision events, which involve large numbers of newly created particles, and are among the dominant processes at the Large Hadron Collider (LHC).
Now that a Higgs boson has been discovered at the LHC, the existence (or non-existence) of supersymmetric particles is of the utmost interest and significance, both theoretically and experimentally. In addition, multi-jet collision events are an important background process for a wide range of analyses, including searches for supersymmetry.

Nominated as an outstanding PhD thesis by the University of Oxford, UK Provides a broad and clear introduction to the experimental and theoretical basis common to a large number of ATLAS analyses Presents an accessible breakdown of one of the benchmark ATLAS supersymmetry searches, which is also a key in future data-taking runs Includes a detailed explanation of its companion standard model background measurement, including all the analysis steps and figures Includes supplementary material: sn.pub/extras
