Exodus: Hidden origin of dark matter and baryons
James Unwin
We propose a new framework for explaining the proximity of the baryon and dark matter relic densities Ω_{DM} \approx 5Ω_B. The scenario assumes that the number density of the obser…
R-symmetric High Scale Supersymmetry
James Unwin
Introducing an R-symmetry to models of high scale supersymmetry (SUSY) can have interesting consequences, and we focus on two aspects. If Majorana masses are forbidden by an R-symm…
The impact of heavy-quark loops on LHC dark matter searches
Ulrich Haisch, Felix Kahlhoefer, James Unwin
If only tree-level processes are included in the analysis, LHC monojet searches give weak constraints on the dark matter-proton scattering cross section arising from the exchange o…
Precision Unification in λSUSY with a 125 GeV Higgs
Edward Hardy, John March-Russell, James Unwin
It is challenging to explain the tentative 125 GeV Higgs signal in the Minimal Supersymmetric Standard Model (MSSM) without introducing excessive fine-tuning, and this motivates th…
Closing in on Asymmetric Dark Matter I: Model independent limits for interactions with quarks
John March-Russell, James Unwin, Stephen M. West
It is argued that experimental constraints on theories of asymmetric dark matter (ADM) almost certainly require that the DM be part of a richer hidden sector of interacting states…
