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…
Kaluza-Klein Dark Matter, Electrons and Gamma Ray Telescopes
Edward A. Baltz, Dan Hooper
Kaluza-Klein dark matter particles can annihilate efficiently into electron-positron pairs, providing a discrete feature (a sharp edge) in the cosmic spectrum at an energ…
Probing Quantum Decoherence with High-Energy Neutrinos
Dan Hooper, Dean Morgan, Elizabeth Winstanley
We consider the prospects for observing the effects of quantum decoherence in high-energy (TeV-PeV) neutrinos from astrophysical sources. In particular, we study Galactic sources o…
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…
Indirect Searches for Kaluza-Klein Dark Matter
Dan Hooper
In this talk, we discuss the potential for the indirect detection of Kaluza-Klein dark matter using neutrino telescopes and cosmic positron experiments. We find that future kilomet…
Searching for Dark Matter with Future Cosmic Positron Experiments
Dan Hooper, Joseph Silk
Dark matter particles annihilating in the Galactic halo can provide a flux of positrons potentially observable in upcoming experiments, such as PAMELA and AMS-02. We discuss the sp…
