Book Description
Cold Dark Matter is believed to constitute almost a quarter of the Universe, most likely in the form of Weakly Interacting Massive Particles (WIMPs), predicted by supersymmetry. This thesis describes the simulation methods, analysis techniques, and results for the calibration of the DRIFT-IIA directional dark matter detector. This is the first module in an array of gas time projection chambers capable of searching for WIMPs with directional sensitivity, located in the Boulby mine. Future operation, development and expansion of the DRIFT-II array will lead to increased potential for directional dark matter detection.

Book Description
Astronomical and cosmological evidence suggests that 27% of the energy content of the universe is in the form of non-baryonic matter referred to as "dark matter." Weakly interacting massive particles have long been considered attractive candidates for this dark matter and can be found in a wide variety of models of physics beyond the Standard Model. The Dark Matter Time Projection Chamber experiment uses low-pressure gas time projection chambers to search for nuclear recoils caused by interactions between nuclei inside a detector and weakly interacting massive particles in the dark matter halo of the Milky Way galaxy. These detectors are also able to reconstruct the directions of these nuclear recoils, allowing for better rejection of possible background events. This thesis describes the design of a small prototype detector and the strategies used by the DMTPC collaboration to reconstruct events, reject backgrounds, and identify nuclear recoil candidate events. It presents the results of several studies aimed at understanding background events in DMTPC detectors. Finally, this work will present the first results from a nuclear recoil search taken with this detector in a surface laboratory at MIT.

Book Description
This thesis covers several theoretical aspects of WIMP (weakly interacting massive particles) dark matter searches, with a particular emphasis on colliders. It mainly focuses on the use of effective field theories as a tool for Large Hadron Collider (LHC) searches, discussing in detail the issue of their validity, and on simplified dark matter models, which are receiving a growing attention from the physics community. It highlights the theoretical consistency of simplified models, which is essential in order to correctly exploit their potential and for them to be a common reference when comparing results from different experiments. This thesis is of interest to researchers (both theorists and experimentalists) in the field of dark matter searches, and offers a comprehensive introduction to dark matter and to WIMP searches for students and non-experts.

Book Description
This study edition of Blum and Rolandi's successful book addresses those students who want to begin to understand particle detection and drift chambers, by providing a solid foundation for judging the achievable accuracy for coordinate and ionization measurements. It covers topics such as gas ionization by particles and by laser rays; the drift of electrons and ions in gases; electrostatics of wire grids and field cages; amplification of ionization; creation of the signal track parameters and their errors; ion gates; particle identification by measurement of ionization; existing chambers; drift chamber gas. The topics are treated in a text-book style with many figures, together with explicitly performed calculations.

Book Description
This thesis describes the search for Dark Matter at the LHC in the mono-jet plus missing transverse momentum final state, using the full dataset recorded in 2012 by the ATLAS Experiment. It is the first time that the number of jets is not explicitly restricted to one or two, thus increasing the sensitivity to new signals. Instead, a balance between the most energetic jet and the missing transverse momentum is required, thus selecting mono-jet-like final states. Collider searches for Dark Matter have typically used signal models employing effective field theories (EFTs), even when comparing to results from direct and indirect detection experiments, where the difference in energy scale renders many such comparisons invalid. The thesis features the first robust and comprehensive treatment of the validity of EFTs in collider searches, and provides a means by which the different classifications of Dark Matter experiments can be compared on a sound and fair basis.
