1. McLean, Kayla Dawn. Search for dark matter produced in association with a Z boson in the ATLAS detector at the Large Hadron Collider.

Degree: Department of Physics and Astronomy, 2021, University of Victoria

This dissertation presents a search for dark matter particles produced in association with a Z boson in proton-proton collisions. The dataset consists of 139 fb-1 of collision events with centre-of-mass energy of 13 TeV, and was collected by the ATLAS detector from 2015-2018 at the Large Hadron Collider. Signal region events are required to contain a Z boson that decays leptonically to either e+e- or μ+μ-, and a significant amount of missing transverse momentum, which indicates the presence of undetected particles. Two types of dark matter models are studied: (1) simplified models with an s-channel axial-vector or vector mediator that couples to dark matter Dirac fermions, and (2) two-Higgs-doublet models with an additional pseudo-scalar that couples to dark matter Dirac fermions. The main Standard Model background sources are ZZ, WZ, non-resonant l+l-, and Z+jets processes, which are estimated using a combination of data and/or simulation. A new reweighting technique is developed for estimating the Z+jets background using γ+jets events in data; the resulting estimate significantly improves on the statistical and systematic errors compared to the estimate obtained from simulation. The observed data in the signal region are compared to Standard Model prediction using a transverse mass discriminant distribution. No significant excess in data is observed for the simplified models and two-Higgs-doublet models studied. A statistical analysis is performed and several exclusion limits are set on the parameters of the dark matter models. Results are compared to direct detection experiments, the CMS experiment, and other ATLAS searches. Prospects and improvements for future iterations of the search are also presented. Advisors/Committee Members: Lefebvre, Michel (supervisor).

2. Jiruška, Daniel. Rodinný dům Rudoltice: Family house - Rudoltice.

Degree: 2019, Brno University of Technology

The aim of the Bachelor thesis is the project documentation for the execution of the basement building. This is a family house, located in the village of Rudoltice in the district of Ústí nad Orlicí. The family house consists of two floors and serves to permanent living of a four-member family and to run a hairdresser. The main entrance to the building is located in a basement between a separate entrance to the hairdresser and a garage, which is designed for one car. The rest of the basement serves predominantly for storage and technical background. The above-ground floor is designed exclusively for living and includes an outdoor terrace and loggia. The building is based on strip foundations of plain concrete and permanent formwork. The basement of the building is designed from a permanent formwork DEK and brick ceramic blocks POROTHERM. The above-ground floor is designed as a wooden building constructed of wooden panels NOVATOP from cross laminated timber. Ceiling structures above the basement are designed from the POROTHERM system using ceiling beams POT and ceiling inserts MIAKO. The ceiling and roof structures of the wooden part of the building are designed from wooden panels NOVATOP ELEMENT. The entire building is roofed with a ventilated roof composed of the two roof planes. Advisors/Committee Members: Eliáš, Luboš (advisor), Klvaňa, Jiří (referee).
