1. Freeze-in dark matter from a sub-Higgs mass clockwork sector via the Higgs portal / Kim, Jinsu ; McDonald, John
The clockwork mechanism allows extremely weak interactions and small mass scales to be understood in terms of the structure of a theory. [...]
Published in Physical Review D 98 (2018) 10.1103/PhysRevD.98.123503 arXiv:1804.02661
2. Clockwork Higgs portal model for freeze-in dark matter / Kim, Jinsu ; McDonald, John
The clockwork mechanism can explain interactions which are dimensionally very weak without the need for very large mass scales. [...]

3. The 750 GeV resonance as non-minimally coupled inflaton: Unitarity violation and why the resonance is a real singlet scalar / McDonald, John
The 750 GeV resonance observed by ATLAS and CMS may be explained by a gauge singlet scalar. [...]

4. Warm dark matter via ultra-violet freeze-in: reheating temperature and non-thermal distribution for fermionic Higgs portal dark matter / McDonald, John
Warm dark matter (WDM) of order keV mass may be able to resolve the disagreement between structure formation in cold dark matter simulations and observations. [...]

5. Signatures of Planck corrections in a spiralling axion inflation model / McDonald, John
The minimal sub-Planckian axion inflation model accounts for a large scalar-to-tensor ratio via a spiralling trajectory in the field space of a complex field Φ [...]

6. A minimal sub-Planckian axion inflation model with large tensor-to-scalar ratio / McDonald, John
We present a minimal axion inflation model which can generate a large tensor-to-scalar ratio while remaining sub-Planckian. [...]

7. Sub-Planckian two-field inflation consistent with the Lyth bound / McDonald, John
The BICEP2 observation of a large tensor-to-scalar ratio, r = 0.20+0.07-0.05, implies that the inflaton ϕ in single-field inflation models must satisfy ϕ ∼ 10MPl in order to produce sufficient inflation. [...]
