Plasma dark matter direct detection
Jackson D. Clarke, Robert Foot
Dark matter in spiral galaxies like the Milky Way may take the form of a dark plasma. Hidden sector dark matter charged under an unbroken gauge interaction provides a simpl…
How to avoid unnatural hierarchical thermal leptogenesis
Jackson D. Clarke
A one-flavour naturalness argument suggests that the Type I seesaw model cannot naturally explain neutrino masses and the baryon asymmetry of the Universe via hierarchical thermal…
DFSZ: a technically natural non-supersymmetric model of neutrino masses, baryogenesis, the strong CP problem, and dark matter
Jackson D. Clarke, Raymond R. Volkas
We describe a minimal extension of the standard model by three right-handed neutrinos, a scalar doublet, and a scalar singlet (the "DFSZ") which serves as an existence proof tha…
Natural leptogenesis and neutrino masses with two Higgs doublets
Jackson D. Clarke, Robert Foot, Raymond R. Volkas
The minimal Type I see-saw model cannot explain the observed neutrino masses and the baryon asymmetry of the Universe via hierarchical thermal leptogenesis without ceding naturalne…
Constraining portals with displaced Higgs decay searches at the LHC
Jackson D. Clarke
It is very easy to write down models in which long-lived particles decaying to standard model states are pair-produced via Higgs decays, resulting in the signature of approximately…
Electroweak naturalness in three-flavour Type I see-saw and implications for leptogenesis
Jackson D. Clarke, Robert Foot, Raymond R. Volkas
In the Type I see-saw model, the naturalness requirement that corrections to the electroweak parameter not exceed 1 TeV results in a rough bound on the lightest right-handed ne…
