TeV gamma-rays and the largest masses and annihilation cross sections of neutralino dark matter
Stefano Profumo
Motivated by the interpretation of the recent results on the TeV gamma radiation from the Galactic center, including the new 2004 HESS data, as a by-product of dark matter particle…
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…
Gluino Annihilations and Neutralino Dark Matter
S. Profumo, C. E. Yaguna
We consider supersymmetric scenarios, compatible with all cosmological and phenomenological requirements, where the lightest SUSY particles (LSPs) are the neutralino and a quasi de…
Non-Universal Gaugino Masses and the Fate of mu -> e gamma
Stefano Profumo, Carlos E. Yaguna
We study charged lepton flavor violating processes in the context of supersymmetric models with non-universal gaugino masses. We consider the generic case of free gaugino masses, a…
