  4. 7. Extensions of general relativity : scalar tensor theory, topology of space-time and supergravity

    Author : Ulf Lindström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This report together with Papers 1—11 constitute a dissertation on the subjects of Scalar Tensor Theories, Topology of Space-Time and Supergravity. These three areas are briefly introduced for providing a background to the work in 1—11. A general discussion of motivations for modifications of the Einstein theory is also offered. . 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. 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
