A Holographic Perspective on the Axion Quality Problem
Peter Cox, Tony Gherghetta, Minh D. Nguyen
The axion provides a compelling solution to the strong CP problem as well as a candidate for the dark matter of the universe. However, the axion solution relies on the spontaneous…
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 ex…
Radion Dynamics and Phenomenology in the Linear Dilaton Model
Peter Cox, Tony Gherghetta
We investigate the properties of the radion in the 5D linear dilaton model arising from Little String Theory. A Goldberger-Wise type mechanism is used to stabilise a large interbra…
A Common Origin for the QCD Axion and Sterile Neutrinos from Strong Dynamics
Peter Cox, Tony Gherghetta, Arpon Paul
We identify the QCD axion and right-handed (sterile) neutrinos as bound states of an chiral gauge theory with Peccei-Quinn (PQ) symmetry arising as a global symmetry of the…
LHC Search for Right-handed Neutrinos in Models
Peter Cox, Chengcheng Han, Tsutomu T. Yanagida
We consider right-handed neutrino pair production in generic models. We propose a new, model-independent analysis using final states containing a pair of same-sign muons…
Precise predictions and new insights for atomic ionisation from the Migdal effect
Peter Cox, Matthew J. Dolan, Christopher McCabe +1
The scattering of neutral particles by an atomic nucleus can lead to electronic ionisation and excitation through a process known as the Migdal effect. We revisit and improve upon…
