  1. 21. Supersymmetric Localization : A Journey from Seven to Three Dimensions

    Författare :Konstantina Polydorou; Guido Festuccia; Elli Pomoni; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supersymmetry; Localization; Equivariant Cohomology; BPS Operators; Topological Field Theory; Equivariant Twisting; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : Quantum Field Theory has been a dominating framework in elementary particle physics during the last century. Within this framework, supersymmetric theories have attracted a lot of attention due to their mathematical structure, simplicity and insight into the problems of unification, dark matter and hierarchy.

  3. 22. Strings and Particles in Six Dimensions - A perturbative approach to (2,0) theory

    Författare :Erik Flink; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis we give a brief review of the six-dimensional (2,0) theories and how they emerge from the study of string/M-theory. In particular, the A_N version of (2,0) theory is the world-volume theory of N+1 parallel M5-branes in the limit where gravity decouples. LÄS MER

  4. 23. The colour of gluon interactions : Studies of Quantum Chromodynamics in soft and hard processes

    Författare :Nicuşor Tîmneanu; Jochen Bartels; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Fysik; Physics;

    Sammanfattning : Quantum Chromodynamics (QCD) is the theory of the strong interaction, one of the fundamental forces of nature. The interactions between quarks are mediated by gluons, which are the colour-charged gauge fields in QCD. LÄS MER

  5. 24. Maximal Unitarity at Two Loops : A New Method for Computing Two-Loop Scattering Amplitudes

    Författare :Kasper J. Larsen; Lisa Freyhult; David Kosower; Joseph Minahan; Paul Heslop; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amplitudes; NNLO calculations; Quantum Chromodynamics; Unitarity; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : The study of scattering amplitudes beyond one loop is necessary for precision phenomenology for the Large Hadron Collider and may also provide deeper insights into the theoretical foundations of quantum field theory. In this thesis we develop a new method for computing two-loop amplitudes, based on unitarity rather than Feynman diagrams. LÄS MER
