  2. 6. Off-shell, maximal supersymmetry & exceptional geometry

    Author : Anna Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Maximal supersymmetry; pure spinors; exceptional geometry; maximal supergravity; loop amplitudes; 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

  4. 7. Studies in field theory : supersymmetry and torsion potentials

    Author : Johan Grundberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This report contains introductions to and summaries of the papers which constitute my thesis. These papers treat four different topics: The first of these is the superspace treatment of the linear multiplet in six space-time dimensions, in particular the solution of the constraint for this multiplet.

  5. 8. A search for Supersymmetry in final states with two same-flavor opposite-sign leptons, jets and missing transverse momentum with the ATLAS detector

    Author : Giulia Ripellino; Bengt Lund-Jensen; Strandberg Jonas; Mikko Voutilainen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ATLAS; LHC; supersymmetry; Fysik; Physics;

    Abstract : This thesis presents a search for Supersymmetry in final states containing two same-flavor opposite-sign leptons, jets and large missing transverse momentum. The search makes use of 36.1 fb−1 of proton-proton collision data collected at a center-of-mass energy of √s = 13 TeV by the ATLAS detector at the Large Hadron Collider. READ MORE

  6. 9. On applications of manifest, maximal supersymmetry & U-duality

    Author : Anna Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; maximal supergravity; pure spinors; Maximal supersymmetry; loop amplitudes; U-duality; Born-Infeld theory; generalised geometry; high energy particle physics;

    Abstract : Maximal supersymmetry is made manifest through the introduction of the pure spinor formalism. In many ways, this formalism represents a powerful tool in examinations of characteristics of different theories in high energy physics, though it is far from extensively exploited. READ MORE

  7. 10. The Complex World of Superstrings : On Semichiral Sigma Models and N=(4,4) Supersymmetry

    Author : Malin Göteman; Ulf Lindström; Daniel Waldram; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Non-linear sigma models; extended supersymmetry; semichiral superfields; neutral hyperkähler geometry; generalized Kähler geometry; T-duality; vector multiplets; Theoretical Physics; Teoretisk fysik;

    Abstract : Non-linear sigma models with extended supersymmetry have constrained target space geometries, and can serve as effective tools for investigating and constructing new geometries. Analyzing the geometrical and topological properties of sigma models is necessary to understand the underlying structures of string theory. READ MORE
