A bstract In this note, we consider how the bundle geometry of field space interplays with the
covariant phase space methods so as to allow to write results of some generality on the …

This paper explicates the direct empirical significance (DES) of symmetries in gauge theory,
with comparisons to classical mechanics. Given a physical system composed of subsystems …

We develop some ideas about gauge symmetry in the context of Maxwell's theory of
electromagnetism in the Hamiltonian formalism. One great benefit of this formalism is that it …

We consider Yang–Mills theory with a compact gauge group G on Minkowski space R 3, 1
and compare the introduction of masses of gauge bosons using the Stueckelberg and Higgs …

In 1978, Friedberg and Lee introduced the phenomenological soliton bag model of hadrons,
generalizing the MIT bag model developed in 1974 shortly after the formulation of QCD. In …

How should we understand gauge-(in) variant quantities and physical possibility? Does the
redundancy present in gauge theory pose different interpretational issues than those …

This thesis is about conceptual aspects of gauge theories. Gauge theories lie at the heart of
modern physics: in particular, they constitute the standard model of particle physics. At its …

This thesis aims to study a novel solution to the Strong CP Problem. As no experimental
signals of an axion have been found yet, the Nelson-Barr mechanism is gaining more and …

Abstract Experiments at the Large Hadron Collider seek to understand the behavior of the
basic building blocks of the universe. Proton-proton collisions are used to probe high energy …
