  1. 1. Supersymmetry vis-à-vis Observation Dark Matter Constraints, Global Fits and Statistical Issues

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; supersymmetry; cosmology of theories beyond the Standard Model; dark matter; gamma rays; dwarf galaxies; direct detection; statistical techniques; scanning algorithms; genetic algorithms; statistical coverage; NATURAL SCIENCES Physics Astronomy and astrophysics Astroparticle physics; NATURVETENSKAP Fysik Astronomi och astrofysik Astropartikelfysik; NATURAL SCIENCES Physics Astronomy and astrophysics Cosmology; NATURVETENSKAP Fysik Astronomi och astrofysik Kosmologi; NATURAL SCIENCES Physics Elementary particle physics Astroparticle physics; NATURVETENSKAP Fysik Elementarpartikelfysik Astropartikelfysik; teoretisk fysik; Theoretical Physics;

    Abstract : Weak-scale supersymmetry is one of the most favoured theories beyond the Standard Model of particle physics that elegantly solves various theoretical and observational problems in both particle physics and cosmology. In this thesis, I describe the theoretical foundations of supersymmetry, issues that it can address and concrete supersymmetric models that are widely used in phenomenological studies. READ MORE

  2. 2. Phenomenological Studies on Supersymmetry and the Strong Force

    University dissertation from Peter Skands, Hökvägen 14, 227 32 Lund

    Author : Peter Skands; Lunds universitet.; Lund University.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; R-parity violation; Physics; beam remnants; hadronisation; parton showers; underlying event; Supersymmetry; Fysik; QCD; Fysicumarkivet A:2004:Skands;

    Abstract : In this thesis, we first consider the phenomenology of R-parity violating supersymmetric extensions of the Standard Model. Specifically, a large number of Lepton and Baryon Number violating decays of sparticles to particles are implemented in the Pythia event generator. READ MORE

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

    University dissertation from Stockholm : Fysikum

    Author : Per Johansson; Stockholms universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supersymmetry; particle physics; NATURAL SCIENCES Physics Elementary particle physics; NATURVETENSKAP Fysik Elementarpartikelfysik;

    Abstract : 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. READ MORE

  4. 4. Search for Supersymmetry and Large Extra Dimensions with the ATLAS Experiment

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Gabriele Bertoli; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ATLAS; CERN; large extra dimensions; supersymmetry; compressed; squark; neutralino; monojet; ADD; standard model; Physics; fysik;

    Abstract : The Large Hadron Collider is the most powerful particle accelerator built to date. It is a proton-proton and heavy ion collider which in 2015 and 2016 operated at an unprecedented center of mass energy of √s = 13 TeV. The Tile Calorimeter is the ATLAS hadronic calorimeter covering the central region of the detector. READ MORE

  5. 5. Off-shell, maximal supersymmetry & exceptional geometry

    University dissertation from Chalmers University of Technology

    Author : Anna Karlsson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Maximal supersymmetry; maximal supergravity; pure spinors; loop amplitudes; exceptional geometry; U-duality; high energy particle physics;

    Abstract : Two lines of research are presented in this thesis, both with a focus on fundamental properties within the supersymmetric theories of high energy physics. The first features analyses based on the actions for maximal supersymmetric Yang–Mills theory and supergravity, provided by the pure spinor formalism. READ MORE
