1. 1. 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.

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. Silicon Tracking and a Search for Long-lived Particles

   Författare :Rebecca Carney; Samuel Silverstein; Sara Strandberg; Maurice Garcia-Sciveres; Joel Goldstein; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; silicon; silicon tracking; radiation damage; neuromorphic; neuromorphic computing; long-lived particles; susy; rpvll; displaced vertices; pixel; pixel detector; fysik; Physics;

   Sammanfattning : The ATLAS Detector, below the surface of the Swiss-French border, measures the remnants of high-energy proton-proton collisions, accelerated by the Large Hadron Collider (LHC) at CERN. Recently the LHC paused operations, having delivered an integrated luminosity corresponding to 150 fb−1 of data at a centre-of-mass energy of 13 TeV. LÄS MER

5. 4. Instrumentation for silicon tracking at the HL-LHC

   Författare :Rebecca Carney; Samuel Silverstein; Sara Strandberg; Thomas Schön; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Instrumentation; physics; particle physics; atlas; radiation damage; neuromorphic; kalman filter; fysik; Physics;

   Sammanfattning : In 2027 the Large Hadron Collider (LHC) at CERN will enter a high luminosity phase, deliver- ing 3000 fb 1 over the course of ten years. The High Luminosity LHC (HL-LHC) will increase the instantaneous luminosity delivered by a factor of 5 compared to the current operation pe- riod. LÄS MER

7. 5. Exotic Decays of Vector-Like Quarks and Development of a Test Procedure for the ITk Strip Module at the ATLAS Detector for the HL-LHC

   Författare :Thomas Mathisen; Elin Bergeås Kuutmann; Venugopal Ellajosyula; Richard Brenner; Freya Blekman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Standard Model; BSM; Composite Higgs; Fine-tuning; Naturalness; Vector-Like Quarks; HL-LHC; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Sammanfattning : The naturalness problem of the Standard Model (SM) challenges our understanding of the origin of mass. Several theories have been proposed to tackle the problem, one of them is the Composite Higgs Model (CHM) where the Higgs boson of the SM is not an elementary scalar but instead a composite object bound at a confinement scale of a TeV.
