Discriminating the source of high-energy positrons with AMS-02
Miguel Pato, Massimiliano Lattanzi, Gianfranco Bertone
We study the prospects for discriminating between the dark matter (DM) and pulsar origin of the PAMELA positron excess with the Alpha Magnetic Spectrometer AMS-02. We simulate the…
Systematic uncertainties in the determination of the local dark matter density
Miguel Pato, Oscar Agertz, Gianfranco Bertone +2
A precise determination of the local dark matter density and an accurate control over the corresponding uncertainties are of paramount importance for Dark Matter (DM) searches. Usi…
Astrophysical limitations to the identification of dark matter: indirect neutrino signals vis-a-vis direct detection recoil rates
Pasquale D. Serpico, Gianfranco Bertone
A convincing identification of dark matter (DM) particles can probably be achieved only through a combined analysis of different detections strategies, which provides an effective…
The Cosmic Ray Lepton Puzzle
Pierre Brun, Gianfranco Bertone, Marco Cirelli +4
Recent measurements of cosmic ray electrons and positrons by PAMELA, ATIC, Fermi and HESS have revealed interesting excesses and features in the GeV-TeV range. Many possible explan…
