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

    Author : Elin Bergeås Kuutmann; Jörgen Sjölin; Kerstin Jon-And; Sten Hellman; Hans Bøggild; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Search for charged Higgs bosons with tau-lepton signatures at the ATLAS experiment of the Large Hadron Collider and development of novel semiconductor particle detectors

    Author : Eleni Myrto Asimakopoulou; Richard Brenner; Arnaud Ferrar; Elin Bergeås Kuutmann; Paula Collins; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Experimental High Energy Physics (HEP) studies are discussed in the context of exotic particle searches and data analysis techniques and the development and production of suitable detectors. The main covered topics span the aforementioned areas and are primarily related to the ATLAS experiment at the Large Hadron Collider (LHC). READ MORE

  5. 3. Searching for a charged Higgs boson and development of a hardware track trigger with the ATLAS experiment

    Author : Joakim Gradin; Elin Bergeås Kuutmann; Johann Collot; Richard Brenner; Susan Shotkin-Gascon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High energy physics; charged Higgs boson; Particle tracking; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : This thesis describes searches for a heavy charged Higgs boson decaying into a top and bottom quark pair, and the development of a hardware track trigger with theATLAS experiment. The data for the two searches was collected with the ATLAS detector at the Large Hadron Collider(LHC) with pp collision energies of √s = 8 and 13 TeV, and corresponds to an integrated luminosity of 20.

  6. 4. Exploration of extended Higgs sectors, development of a displaced track trigger, and improvements in GRID middleware

    Author : Max Isacson; Elin Bergeås Kuutmann; Patrizia Azzi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; BSM; Supersymmetry; Standard Model; Higgs; 2HDM; Charged Higgs; Compositeness; Pattern Matching; GRID; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : Two possible solutions to the Standard Model (SM) fine-tuning problem are presented in this thesis, MSSM and Compositeness. The Higgs sector of the MSSM can be tested by searching for charged Higgs bosons. Two direct searches for charged Higgs bosons decaying into a top- and bottom-quark are performed using 13.2 and 36.

  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

    Author : Thomas Mathisen; Elin Bergeås Kuutmann; Venugopal Ellajosyula; Richard Brenner; Freya Blekman; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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.
