Kinky vortons in the 2HDM
Richard A. Battye, Steven J. Cotterill, Adam K. Thomasson
We construct and analyse two-dimensional, current-carrying ring solutions, known as kinky vortons, in the -symmetric global two-Higgs-doublet model (2HDM). We demonst…
Spectrum of radiation from global strings and the relic axion density
Richard A. Battye, Lukasz P. Bunio, Steven J. Cotterill +1
We discuss key aspects of the nature of radiation from global strings and its impact on the relic axion density. Using a simple model we demonstrate the dependence on the spectrum…
Vortex stability in pseudo-Hermitian theories
R. A. Battye, S. J. Cotterill, P. Millington
Pseudo-Hermitian (including -symmetric) field theories support phenomenology that cannot be replicated in standard Hermitian theories. We describe a concrete example…
Complete Classification of Domain Wall Solutions in the -symmetric 2HDM
Richard A. Battye, Steven J. Cotterill, Adam K. Thomasson
We present a complete classification of domain wall solutions in the two-Higgs Doublet Model (2HDM) with a global symmetry, categorised as superconducting, CP-violat…
Superconducting strings in the two-Higgs doublet model
Richard Battye, Steven Cotterill
We present superconducting vortex solutions in the two-Higgs doublet model which has a gauged Higgs-family symmetry. We write down an ansatz for the solution and study its b…
Near-Peak Spectrum of Gravitational Waves from Collapsing Domain Walls
Bryce Cyr, Steven Cotterill, Richard Battye
Cosmological domain walls appear in many well-motivated extensions to the standard model of particle physics. If produced, they quickly enter into a self-similar scaling regime, wh…
