Neutralino Dark Matter Detection in Split Supersymmetry Scenarios
Antonio Masiero, Stefano Profumo, Piero Ullio
We study the phenomenology of neutralino dark matter within generic supersymmetric scenarios where the Gaugino and Higgsino masses are much lighter than the scalar soft breaking ma…
The Role of Antimatter Searches in the Hunt for Supersymmetric Dark Matter
Stefano Profumo, Piero Ullio
We analyze the antimatter yield of supersymmetric (SUSY) models with large neutralino annihilation cross sections. We introduce three benchmark scenarios, respectively featuring bi…
Neutralino Relic Density Enhancement in Non-Standard Cosmologies
Stefano Profumo, Piero Ullio
The thermal relic abundance of species critically depends on the assumed underlying cosmological model. In the case of neutralinos, freeze-out takes place long before Big Bang Nucl…
Gamma-Ray Summary Report
J. Buckley, T. Burnett, G. Sinnis +7
This paper reviews the field of gamma-ray astronomy and describes future experiments and prospects for advances in fundamental physics and high-energy astrophysics through gamma-ra…
Cosmic antiprotons as a probe for neutralino dark matter?
Lars Bergstrom, Joakim Edsjo, Piero Ullio
The flux of cosmic ray antiprotons from neutralino annihilations in the galactic halo is computed for a large sample of models in the Minimal Supersymmetric extension of the Standa…
Signatures of exotic physics in antiproton cosmic ray measurements
Piero Ullio
More than a decade ago it was noticed that an unexpectedly large value of the measured cosmic antiproton flux at low kinetic energies could be interpreted in terms of a neutralino-…
