  3. 2. Search for Pair-Produced Supersymmetric Top Quark Partners with the ATLAS Experiment

    Författare :Yiming Abulaiti; Sara Strandberg; Kerstin Jon-And; Isabell Melzer-Pellmann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; supersymmetry; SUSY; Beyond Standard Model; stop; pMSSM; Large Hadron Collider; LHC; CERN; fysik; Physics;

    Sammanfattning : Searches for the supersymmetric partner of the top quark (stop) are motivated by natural supersymmetry, where the stop has to be light to cancel the large radiative corrections to the Higgs boson mass. This thesis presents three different searches for the stop at √s = 8 TeV and √s = 13 TeV using data from the ATLAS experiment at CERN’s Large Hadron Collider. LÄS MER

  4. 3. 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

  5. 4. Top Quark Pair Production in ATLAS

    Författare :Karl Gellerstedt; Jörgen Sjölin; Kerstin Jon-And; Cecilia Gerber; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; particle physics; top quark; LHC; ATLAS; fysik; Physics;

    Sammanfattning : The Large Hadron Collider (LHC) at the international particle physics laboratory CERN in Switzerland is currently the most powerful particle accelerator on earth. This thesis presents analyses of proton-proton collisions at the energy √s = 7 TeV, recorded by ATLAS, one of the detectors at the LHC. LÄS MER

  7. 5. Search for Supersymmetry with DELPHI, and preparation for ATLAS

    Författare :Per Johansson; Kerstin Jon-And; Klas Hultqvist; Anna Lipniacka; Ritva Kinnunen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; supersymmetry; particle physics; Elementary particle physics; Elementarpartikelfysik;

    Sammanfattning : This thesis reports on searches for supersymmetric particles, in particular neutralinos, conducted with the DELPHI detector at the LEP accelerator at CERN. The searches were performed within the framework of the Minimal Supersymmetric Standard Model (MSSM), with R-parity conserved and gravity mediated supersymmetry breaking. LÄS MER
