Q-ball collisions and their Gravitational Waves
Deog Ki Hong, Stephen J. Lonsdale
Sydney Coleman's Q-ball remains a compelling instance of localised object formation within classical field theory, independently of the quantum evolution. The theoretical possibili…
Magnetic axion vortex and very light QCD axions
Deog Ki Hong, Stephen J. Lonsdale
We show that a stable vortex soliton, carrying a constant magnetic flux, exists in the homogeneous medium of axions with a constant time-derivative. Axions can be bound in the vort…
Comprehensive asymmetric dark matter model
Stephen J. Lonsdale, Raymond R. Volkas
Asymmetric dark matter (ADM) is motivated by the similar cosmological mass densities measured for ordinary and dark matter. We present a comprehensive theory for ADM that addresses…
Asymmetric Dark Matter and the hadronic spectra of hidden QCD
Stephen J. Lonsdale, Martine Schroor, Raymond R. Volkas
The idea that dark matter may be a composite state of a hidden nonabelian gauge sector has received great attention in recent years. Frameworks such as asymmetric dark matter motiv…
Unified dark matter with intermediate symmetry breaking scales
Stephen J. Lonsdale
Asymmetric symmetry breaking models dynamically break the G X G gauge symmetries of mirror models to distinct subgroups in the two sectors. The coincidental abundances of visible a…
Grand unified hidden-sector dark matter
Stephen J. Lonsdale, Raymond R. Volkas
We explore GxG unified theories with the visible and the hidden or dark sectors paired under a Z2 symmetry. Developing a system of 'asymmetric symmetry breaking' we motivate such m…
