  1. 1. Cluster Effective Field Theory

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :EMIL RYBERG; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; effective field theory; charge radius; resonant state; renormalization; radiative capture; halo nuclei; power counting; nuclear physics; few-body physics;

    Sammanfattning : Halo nuclei are loosely bound systems consisting of a core plus valence nucleon(s). In so called Halo, or Cluster, effective field theory, the core of the halo nucleus is treated as an effective degree-of-freedom without internal structure. LÄS MER

  2. 2. Aspects of Yang-Mills Theory Solitons, Dualities and Spin Chains

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Lisa Freyhult; Uppsala universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Theoretical Physics; Field theory; String theory; Yang-Mills; Effective models; Supersymmetry; Solitons; Fermion number; Duality; AdS CFT correspondence; Bethe ansatz; Teoretisk fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Sammanfattning : One of the still big problems in the Standard Model of particle physics is the problem of confinement. Quarks or other coloured particles have never been observed in isolation. Quarks are only observed in colour neutral bound states. The strong interactions are described using a Yang-Mills theory. LÄS MER

  3. 3. Effective Field Theory and One-proton Halo Nuclei

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :EMIL RYBERG; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radiative capture; halo nuclei; effective field theory; nuclear physics; charge radius;

    Sammanfattning : In this thesis we present formalism for treating one-proton halo nuclei in effective field theory. Halo nuclei are loosely bound systems consisting of a core plus valence nucleon(s). In so called Halo, or Cluster, effective field theory, the core of the halo nucleus is treated as a structureless, effective degree-of-freedom. LÄS MER

  4. 4. Top quark and heavy vector boson associated production at the ATLAS experiment Modelling, measurements and effective field theory

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Olga Bessidskaia Bylund; Stockholms universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Sammanfattning : The Standard Model (SM) of particle physics describes the elementary particles that constitute matter and their interactions. The predictions of the SM have been confirmed by numerous experimental results. LÄS MER

  5. 5. Field Theories and Vortices with Nontrivial Geometry

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

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

    Sammanfattning : 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.
