Dark Matter Interpretations of the Electron/Positron Excesses after FERMI
Speaker(s): Alessandro Strumia
Abstract: The cosmic-ray excess observed by PAMELA in the positron fraction and by FERMI and HESS in the electron + positron flux can be interpreted in terms of DM annihilations or decays into leptonic final states. Final states into tau's or 4mu give the best fit to the excess. However, in the annihilation s... read more
