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-…
