  2. 1. Search for Charginos and Sleptons in ATLAS and Identification of Pile-up with the Tile Calorimeter

    Author : Pawel Klimek; Christophe Clément; Barbro Åsman; Freya Blekman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ATLAS experiment; particle physics; high energy physics; supersymmetry; SUSY; beyond standard model; chargino; neutralino; slepton; vector boson fusion; VBF; Tile calorimeter; TileCal; pile-up; quality factor; Large Hadron Collider; LHC; CERN; fysik; Physics;

    Abstract : The standard model of particle physics (SM) describes the elementary particles and their interactions. Supersymmetry (SUSY), a symmetry beyond those included in the standard model could resolve some of the SM shortcomings. It can provide a candidate for Dark Matter and a solution to the hierarchy problem. READ MORE

  4. 2. Search for Direct Top Squark Pair Production with the ATLAS Experiment and Studies of the Primary Vertex Reconstruction Performance

    Author : Yiming Abulaiti; Sara Strandberg; Robert Wagner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SUSY;

    Abstract : The ATLAS detector is one of the two largest experiments installed at the Large Hadron Collider at CERN, the European Organization for Nuclear Research. During the first run, the ATLAS detector recorded data at centre of mass energies of 7 TeV and 8 TeV, enabling many precision measurements and new physics searches. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. Silicon Tracking and a Search for Long-lived Particles

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

    Abstract : 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. READ MORE

  7. 5. Luminosity determination and searches for supersymmetric sleptons and gauginos at the ATLAS experiment

    Author : Anders Floderus; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electroweak; SUSY; Supersymmetry; Luminosity; LUCID; LHC; ATLAS; Slepton; Gaugino; Fysicumarkivet A:2014:Floderus;

    Abstract : This thesis documents my work in the luminosity and supersymmetry groups of the ATLAS experiment at the Large Hadron Collider. The theory of supersymmetry and the concept of luminosity are introduced. The ATLAS experiment is described with special focus on a luminosity monitor called LUCID. READ MORE
