  1. 1. Yang-Mills Theory in Gauge-Invariant Variables and Geometric Formulation of Quantum Field Theories

    Författare :Sergey Slizovskiy; Antti Niemi; Andrey Losev; Andrey Marshakov; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Yang-Mills theory; spin-charge separation; Kaluza-Klein theory; branes; curved beta-gamma systems; Mathematical physics; Matematisk fysik; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : In Part I we are dealing with effective description of Yang-Mills theories based on gauge-invarint variables. For pure Yang-Mills we study the spin-charge separation varibles. The dynamics in these variables resembles the Skyrme-Faddeev model. LÄS MER

  3. 2. BRST and Topological Gauge Theories

    Författare :Niclas Sandström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gauge theory; BRST-quantization; topological field theory; BV-quantization; almost product structure APS ; superfield formulation;

    Sammanfattning : In this thesis, the BRST-quantization of gauge theories is discussed. A detailed analysis of the BRST-quantization on inner product spaces is performed for a class of abelian models, including reparametrization invariant ones. General rules how to obtain physical wave functions and propagators are proposed. LÄS MER

  4. 3. Phenomenological studies of dimensional deconstruction

    Författare :Tomas Hällgren; Tommy Ohlsson; Stefan Antusch; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dimensional deconstruction; higher-dimensional gauge theories; neu- trino mixing; neutrino oscillations; universal extra dimensions; ADD models; Ka- luza{Klein dark matter; Other physics; Övrig fysik;

    Sammanfattning : In this thesis, two applications of dimensional deconstruction are studied. The first application is a model for neutrino oscillations in the presence of a large decon- structed extra dimension. In the second application, Kaluza{Klein dark matter from a latticized universal extra dimension is studied. The goal of these projects have been twofold. LÄS MER

  5. 4. Aspects of Dimensional Deconstruction and Neutrino Physics

    Författare :Tomas Hällgren; Tommy Ohlsson; Stephan J. Hubber; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dimensional deconstruction; higher-dimensional gauge theories; discretized gravity; neutrino mass; neutrino mixing; neutrino oscillations; Engineering physics; Teknisk fysik;

    Sammanfattning : The existence of at or curved extra spatial dimensions provides new insights into several of the problems which face the Standard Model of particle physics, including the gauge hierarchy problem, the smallness of neutrino masses, and the dark matter problem. However, higher-dimensional gauge theories are not renormalizable and can only be considered as low-energy effective theories, with limited applicability. LÄS MER
