1. 16. Emittance and Energy Diagnostics for Electron Beams with Large Momentum Spread

   Författare :Maja Olvegård; Volker Ziemann; Kay Wittenburg; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; beam instrumentation; particle beam diagnostic; emittance; particle collider; particle accelerator; High Energy Physics; Högenergifysik;

   Sammanfattning : Following the discovery of the Higgs-like boson at the Large Hadron Collider, there is demand for precision measurements on recent findings. The Compact Linear Collider, CLIC, is a candidate for a future linear electron-positron collider for such precision measurements. LÄS MER

3. 17. 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.

4. 18. Search for Supersymmetry and Large Extra Dimensions with the ATLAS Experiment

   Författare :Gabriele Bertoli; Christophe Clement; Martijn Mulders; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; CERN; large extra dimensions; supersymmetry; compressed; squark; neutralino; monojet; ADD; standard model; fysik; Physics;

   Sammanfattning : The Large Hadron Collider is the most powerful particle accelerator built to date. It is a proton-proton and heavy ion collider which in 2015 and 2016 operated at an unprecedented center of mass energy of √s = 13 TeV. The Tile Calorimeter is the ATLAS hadronic calorimeter covering the central region of the detector. LÄS MER

5. 19. 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

7. 20. Calibration of the ATLAS calorimeters and discovery potential for massive top quark resonances at the LHC

   Författare :Elin Bergeås Kuutmann; Jörgen Sjölin; Kerstin Jon-And; Sten Hellman; Hans Bøggild; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; particle physics; the ATLAS experiment; the Large Hadron Collider; calorimeter; calorimetry; hadronic calibration; top quark; top quark pair resonances; search for physics beyond the Standard Model; Elementary particle physics; Elementarpartikelfysik; Physics; Fysik; fysik; Physics;

   Sammanfattning : ATLAS is a multi-purpose detector which has recently started to take data at the LHC at CERN. This thesis describes the tests and calibrations of the central calorimeters of ATLAS and outlines a search for heavy top quark pair resonances. LÄS MER
