Asymmetric Dark Matter via Spontaneous Co-Genesis
John March-Russell, Matthew McCullough
We investigate, in the context of asymmetric dark matter (DM), a new mechanism of spontaneous co-genesis of linked DM and baryon asymmetries, explaining the observed relation betwe…
On the DAMA and CoGeNT Modulations
Mads T. Frandsen, Felix Kahlhoefer, John March-Russell +3
DAMA observes an annual modulation in their event rate, as might be expected from dark matter scatterings, while CoGeNT has reported evidence for a similar modulation. The simplest…
A Supersymmetric One Higgs Doublet Model
Rhys Davies, John March-Russell, Matthew McCullough
We present a supersymmetric extension of the Standard Model in which only one electroweak doublet acquires a vacuum expectation value and gives mass to Standard Model fermions. As…
