Gauge Mediated Supersymmetry Breaking and Multi-TeV Gamma-Rays from the Galactic Center
Dan Hooper, John March-Russell
Recently, the HESS telescope has observed a gamma-ray spectrum from the galactic center extending to at least 10 TeV. Although it has been suggested that this could be the pr…
Asymmetric Sneutrino Dark Matter and the Omega(b)/Omega(DM) Puzzle
Dan Hooper, John March-Russell, Stephen M. West
The inferred values of the cosmological baryon and dark matter densities are strikingly similar, but in most theories of the early universe there is no true explanation of this fac…
A Simple Model of Neutrino Masses from Supersymmetry Breaking
John March-Russell, Stephen West
We analyze a class of supersymmetric models first introduced by Arkani-Hamed et al and Borzumati et al in which the light neutrino masses result from higher-dimensional supersymmet…
TeV scale resonant leptogenesis from supersymmetry breaking
Thomas Hambye, John March-Russell, Stephen M. West
We propose a model of TeV-scale resonant leptogenesis based upon recent models of the generation of light neutrino masses from supersymmetry-breaking effects with TeV-scale right-h…
