  1. 1. The GLAST Satellite Calorimeter

    Författare :Georg Johansson; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GLAST; CsI Tl crystals; electromagnetic calorimeter; hodoscopic assembly; satellite-born detector; Dark Matter; cosmic gamma radiation;

    Sammanfattning : The Gamma Ray Large Area Space Telescope (GLAST) is a multi-national satellite mission with aim to study the high-energy gamma ray sky. The main instrument is the Large Area Telescope (LAT) that consists of 16 towers, each housing a silicon strip precision tracker and a CsI(Tl) calorimeter. LÄS MER

    Sammanfattning : The Large Hadron Collider at CERN is scheduled to undergo upgrades in 2026-2028 to significantly increase its luminosity. These upgrades, while providing the experiments with a higher collision rate, pose a number of challenges to the design of the hardware and software in the detectors. LÄS MER

  4. 3. Search for Stop Using the ATLAS Detector and Performance Analysis of the Tile Calorimeter with Muons from W Decays

    Författare :Stefio Yosse Andrean; Christophe Clement; Joakim Edsjö; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; particle physics; standard model; bsm; supersymmetry; stop; calorimeter; ATLAS; fysik; Physics;

    Sammanfattning : This thesis presents a search for the supersymmetric partner of the top quark in the final state with one lepton. The search focuses especially in the region of the parameter space where the 2-body decay dominates. The analysis is performed using LHC full Run 2 data at √s = 13 TeV as recorded by the ATLAS detector. LÄS MER

  5. 4. 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

  7. 5. Search for New Scalar Particles with ATLAS

    Författare :Stefio Yosse Andrean; Christophe Clement; Sara Strandberg; Markus Klute; Stockholms universitet; []
