Nominated as an outstanding PhD thesis by the CERN, Geneva
Winner of ATLAS thesis award 2016 Provides in-depth descriptions of analysis techniques and challenges particularly relevant for but not restricted to the mono-jet signature Documents cutting-edge results from the Large Hadron Collider run-1 in the search for WIMPs as dark matter candidates in the mono-jet signature, embedded in the overall scientific context beyond particle physics Includes a detailed description of the run-1 ATLAS Central Trigger, important operational challenges, and its upgrade for Large Hadron Collider run-2
This thesis describes in detail a search for weakly interacting massive particles as possible dark matter candidates, making use of so-called mono-jet events. It includes a detailed description of the run-1 system, important operational challenges, and the upgrade for run-2. The nature of dark matter, which accounts for roughly 25% of the energy-matter content of the universe, is one of the biggest open questions in fundamental science. The analysis is based on the full set of proton-proton collisions collected by the ATLAS experiment at the Large Hadron Collider at √s = 8 TeV. Special attention is given to the experimental challenges and analysis techniques, as well as the overall scientific context beyond particle physics. The results complement those of non-collider experiments and yield some of the strongest exclusion bounds on parameters of dark matter models by the end of the Large Hadron Collider run-1.
Details of the upgrade of the ATLAS Central Trigger for run-2 are also included.
