Dark Matter (Theory/Experiment) Parallel

There is overwhelming evidence that non-baryonic dark matter constitutes ~27% of the energy density of the universe. Weakly Interacting Massive Particles (WIMPs) are promising dark matter candidates that may produce gamma rays via annihilation or decay detectable by the Fermi Large Area Telescope (Fermi LAT). A detection of WIMPs would also indicate the existence of physics beyond the...

Dark Matter (Theory/Experiment) Parallel

It is likely that observation of dark matter annihilation radiation will be made from the source that provides the largest signal to noise ratio. It is desirable, however, that dark matter annihilation radiation be seen from multiple sources. Not only would it provide independent verification of the phenomenon, but it would break degeneracies in uncertainties inherent with calculations of the...

Dark Matter (Theory/Experiment) Parallel

The cubic-kilometer sized IceCube neutrino observatory, constructed in the glacial ice at the South Pole, offers new opportunities for neutrino physics with its in-fill array "DeepCore". IceCube searches indirectly for dark matter via neutrinos from dark matter self-annihilations and has a high discovery potential through striking signatures. We report on the latest results from searches for...

16. Positrons from dark matter in light of recent developments

Dark Matter (Theory/Experiment) Parallel

The presence of an anomalous cosmic-ray positron component at energies coinciding with the favored mass range of dark matter candidates has spurred great interest in the past several years. After surveying current experimental results, we will address the prospects for a dark matter connection, and what channels may remain viable, in the context of recent observational and theoretical...

52. Prospects for Discovery of DM Annihilation to Primary Neutrinos with IceCube

Dark Matter (Theory/Experiment) Parallel

We present sensitivity limits for discovery of dark matter at IceCube/DeepCore from annihilation of solar WIMPs into primary neutrinos. This analysis is motivated by the dominance of prompt neutrino final states in some classes of models beyond the neutralino dark matter. Moreover, solar WIMPs provide the only probe for indirect detection of such models for annihilation rates equal to or below...
