1. 1. Transition Radiation Tracker calibration, searches beyond the Standard Model and multiparticle correlations in ATLAS

   Författare :Alejandro Alonso; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Beyond Standard Model; ATLAS; LHC; Fourth family of quarks; Same-sign top production; Drift tubes; TRT; QCD; Supersymmetry; Inner Detector calibration; Tracking;

   Sammanfattning : This thesis contains two different aspects of my research work towards physics in proton-proton collisions in the ATLAS experiment at the LHC. The first part is focused on the understanding and developing of a calibration system to obtain the best possible charged particle reconstruction in the Transition Radiation Tracker. LÄS MER

3. 2. Searches for New Physics Using Innovative Data Acquisition, Analysis, and Compression Techniques

   Författare :Alexander Ekman; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Particle Physics; Large Hadron collider LHC; ATLAS; Automation; Calibration; Analysis; Dark Matter; Machine Learning ML ; Artificial Intelligence AI ; Data Compression; Open-source;

   Sammanfattning : The high event rate delivered by the Large Hadron Collider (LHC) provides experiments with opportunities for new discoveries as well as challenges related to the large amounts of data recorded. Overcoming this requires innovative techniques in the three topics of this thesis: Data acquisition, data analysis, and data compression. LÄS MER

4. 3. Aspects of the ATLAS ITk Inner Tracker development for the high luminosity upgrade of the Large Hadron Collider

   Författare :Jonas Steentoft; Richard Brenner; Rebeca Gonzalez Suarez; Matti Kalliokoski; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ATLAS ITk; Detector instrumentation; Applied physics; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Sammanfattning : The High Luminosity upgrade of the Large Hadron Collider (HL-LHC), necessitates that the ATLAS experiment replace their current Inner Detector (ID) system. The new Inner Tracker (ITk) will be an all silicon detector, utilising both pixel and strip sensors, with the aim of performing as well, or better than the current system - but in a much more challenging environment.

5. 4. Search for Dark Matter in events with missing transverse momentum and a Higgs boson decaying into bottom quarks with the ATLAS detector

   Författare :Eleni Skorda; Partikel- och kärnfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; LHC; Beyond the Standard Model; RECAST; Missing transverse momentum; Higgs boson; Bottom quarks; Transition Radiation Tracker; Dark Matter; Fysicumarkivet A:2022:Skorda;

   Sammanfattning : Many astrophysical observations indicate the existence Dark Matter, which is not predicted by the Standard Model (SM) of particle physics. Many theories beyond the Standard Model (BSM) predict new heavy particles called WIMPs (Weakly Interacting Massive Particles). LÄS MER

7. 5. Studies of the electronic noise of the Tile Calorimeter and the development of a material map for searches for exotic long-lived particles which decay

   Författare :Filip Backman; David Milstead; Christian Ohm; Klas Hultqvist; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

   Sammanfattning : This thesis contains two major topics related to the ATLAS experiment: the calibration of electronic noise in the tile calorimeter and the development of a detailed map of the material in the inner tracker used in searches for long-lived particles.The noise in TileCal is shown to be consistent with the expectations based on heat and radiation.
