Minimal Flavoured DFSZ Axion Models: Predictive Yukawa Textures and Flavour Constraints
Peter Cox, Maaz Hayat, Raymond R. Volkas
We study a predictive class of flavoured DFSZ axion models in which the Peccei--Quinn symmetry is fully horizontal and the domain wall number is unity. These Minimal F-DFSZ models…
Spin-independent scattering of pseudoscalar-mediated dark matter
Nicole F. Bell, Giorgio Busoni, Peter Cox +6
Dark matter with pseudoscalar couplings provides a well-motivated scenario in which direct-detection signals are suppressed at tree level, since the scattering off nuclei is both s…
Irreducible Constraints on Hadronically Interacting Sub-GeV Dark Matter
Peter Cox, Matthew J. Dolan, Avirup Ghosh
We derive conservative upper limits on the dark-matter--nucleon scattering cross-section for sub-GeV mass dark matter. Working exclusively within the low-energy chiral effective th…
A new idea for relating the asymmetric dark matter mass scale to the proton mass
Peter Cox, Rafael E. Pérez, Raymond R. Volkas
Asymmetric dark matter is a well-motivated approach to explain the apparent coincidence between the relic densities of visible and dark matter, . A complete expl…
Dark Matter Induced Nucleon Decay Through the Neutron Portal
Nicole F. Bell, Peter Cox, Jayden L. Newstead +1
The neutron portal operator provides a theoretically motivated connection between the visible and dark sectors and features in several well-studied asymmetric dark matter models. T…
Photonic Freeze-In
Peter Cox, Matthew J. Dolan, Frederick J. Hiskens
We present a new scenario of freeze-in, where the dark matter is produced exclusively via the annihilation of photons. We study fermionic and scalar dark matter models with a focus…
New Limits on Light Dark Matter-Nucleon Scattering
Peter Cox, Matthew J. Dolan, Joshua Wood
We derive new bounds on hadronically-interacting, sub-GeV mass dark matter. First, we show that one-loop interactions with photons can be sufficient to maintain equilibrium between…
Classification of three-family flavoured DFSZ axion models that have no domain wall problem
Peter Cox, Matthew J. Dolan, Maaz Hayat +2
We provide an exhaustive classification of three-family DFSZ axion models that have no cosmological domain wall problem. This result is obtained by making the Peccei-Quinn symmetry…
