  1. 1. Phenomenology of Inert Scalar and Supersymmetric Dark Matter

    Författare :Erik Lundström; Joakim Edsjö; Lars Bergström; Michel Tytgat; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Dark matter; inert scalars; supersymmetry; indirect detection; accelerator searches; Physics; Fysik; Astroparticle physics; Astropartikelfysik; Elementary particle physics; Elementarpartikelfysik; Theoretical Physics; teoretisk fysik;

    Sammanfattning : While the dark matter has so far only revealed itself through the gravitational influence it exerts on its surroundings, there are good reasons to believe it is made up by WIMPs – a hypothetical class of heavy elementary particles not encompassed by the Standard Model of particle physics. The Inert Doublet Model constitutes a simple extension of the Standard Model Higgs sector. LÄS MER

  2. 2. Calibration of b-tagging efficiency and search for Dark Matter production in association with heavy avour quarks with the ATLAS experiment

    Författare :Anna Shcherbakova; Sara Strandberg; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ATLAS; b-tagging; calibration; Dark Matter; simplified model; High Energy Physics; högenergifysik;

    Sammanfattning : The Large Hadron Collider (LHC) is the most powerful and complex particle accelerator ever built. The ATLAS detector is a general-purpose particle detector at the LHC, designed to cover a wide range of physics measurements. LÄS MER

  3. 3. Searches for Massive Highly Ionising Particles at the ATLAS Experiment and in Polar Volcanic Rocks, and Performance Studies of the First Level ATLAS Trigger System

    Författare :Katarina Bendtz; David Milstead; Kenneth Österberg; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Magnetiska monopoler; Trigger; Physics; fysik;

    Sammanfattning : The Standard Model (SM) of particle physics describes the elementary particles and their interactions. Despite passing a number of high precision falsification tests, it is argued that the SM suffers from a number of shortcomings. Many Beyond the Standard Model (BSM) theories have therefore been postulated. LÄS MER

  4. 4. Search for Supersymmetry with DELPHI, and preparation for ATLAS

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