  1. 1. Dualities, Symmetries and Unbroken Phases in String Theory Probing the Composite Nature of the String

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johan Engquist; Uppsala universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Theoretical Physics; String Theory; M-Theory; Higher Spin Gauge Theory; Super Yang-Mills Theory; Anti-de Sitter Spacetime; Singletons; Massless Higher Spin Gauge Fields; AdS CFT Correspondence; Spin Chains; Semiclassical Strings; Tensionless Limits; Conformal Symmetry; Supersymmetry; Higher Spin Gauge Symmetry; Integrability; Fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : The thesis treats aspects of string/M-theory in anti-de Sitter spacetimes and their supersymmetric completions. By applying the AdS/CFT correspondence, as well as models of spin chains and singletons, we try to attain a better understanding of the underlying symmetries and the unbroken phases of string/M-theory.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; AdS CFT correspondence; holographic principle; supersymmetric localization; Wilson Loops; Theoretical Physics; Teoretisk fysik;

    Abstract : The gauge/string duality, a.k.a. the holographic principle is a profound assertion that emerged from string theory. READ MORE

  3. 3. Phenomenology of new Neutral Vector Bosons and Parton Distributions from Hadronic Fluctuations

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Andreas Ekstedt; Uppsala universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QCD; Higgs; Gauge Symmetry; Standard Model; BFKL; PDF; DIS; Beyond the Standard Model; Colliders; Phenomenology; Effective Potential; Anomaly; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : The Higgs particle was first predicted in 1964, and was discovered in the summer of 2012 at the Large Hadron Collider (LHC). This discovery was the latest in a long list of successful Standard Model predictions spanning the last fifty years. READ MORE

  4. 4. LOST IN LOCALISATION searching for exact results in supersymmetric gauge theories

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Louise Anderson; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extended Supersymmetry; Matrix Models; Large N-techniques; Supersymmetric Gauge Theory; Localisation; Topological Field Theory;

    Abstract : This thesis deals with one of the very basics of theoretical physics: computing observable quantities. In the language commonly used to describe the subatomic world, gauge theories, this problem is far from trivial as the observables are expressed in terms of infinite-dimensional integrals. READ MORE

  5. 5. Field Theories and Vortices with Nontrivial Geometry

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kristel Torokoff; Uppsala universitet.; [2006]
    Keywords : Theoretical physics; theoretical physics; gauge field theory; knot theory; spontaneously broken symmetry; effective model; numerical calculation; soliton; vortex; electromagnetic plasma; Teoretisk fysik;

    Abstract : This thesis investigates aspects of field theories and soliton solutions with nontrivial topology. In particular we explore the following effective models: a limited sector of the scalar Electroweak theory called extended Abelian Higgs model, and a classical mechanics model derived from the low energy SU(2) Yang-Mills theory.
