Gauge Symmetry Breaking in Gauge Theories---In Search of Clarification [PDF]

open access: yes, 2011
The paper investigates the spontaneous breaking of gauge symmetries in gauge theories from a philosophical angle. Local gauge symmetry itself cannot break spontaneously in quantized gauge theories according to Elitzur's theorem---even though the notion ...

Gauge invariant accounts of the Higgs mechanism [PDF]

open access: yes, 2011
The Higgs mechanism gives mass to Yang-Mills gauge bosons. According to the conventional wisdom, this happens through the spontaneous breaking of gauge symmetry.

Weyl’s gauge argument [PDF]

open access: yes, 2013
The standard U(1) “gauge principle” or “gauge argument” produces an exact potential A=dλ and a vanishing field F=ddλ=0. Weyl has his own gauge argument, which is sketchy, archaic and hard to follow; but at least it produces an inexact potential A and a ...

A Partial Elucidation of the Gauge Principle [PDF]

open access: yes, 2008
The elucidation of the gauge principle "is the most pressing problem in current philosophy of physics" Michael Redhead in 2003. This paper argues for two points that contribute to this elucidation in the context of Yang-Mills theories.

Localization of Gauge Theories on the Three-Sphere [PDF]

open access: yes, 2012
We describe the application of localization techniques to the path integral for supersymmetric gauge theories in three dimensions. The localization procedure reduces the computation of the expectation value of BPS observables to a calculation in a matrix

Gauge Mediated Supersymmetry Breaking in Five Dimensions [PDF]

open access: yes, 2011
PhDIn this thesis we focus on the construction of models in which a supersymmetry breaking hidden sector is located on one fixed point of an extra dimensional interval and the effects are gauge mediated across this interval to the other fixed point ...

Topics in Supersymmetry Breaking and Gauge/Gravity Dualities [PDF]

open access: yes, 2010
The thesis covers two topics in string theory and quantum field theory. First, we realize metastable vacua in various supersymmetric gauge theories. Specifically, we consider the Coulomb branch of any N = 2 supersymmetric gauge theory, and perturb it by ...

The pseudoparticle approach for solving path integrals in gauge theories [PDF]

open access: yes, 2005
We present a numerical technique for calculating path integrals in non-compact U(1) and SU(2) gauge theories. The gauge fields are represented by a superposition of pseudoparticles of various types with their amplitudes and color orientations as degrees ...
