Study of positrons from cosmic rays interactions and cold dark matter annihilations in the galactic environment
Roberto A. Lineros
Positron and electron cosmic rays provide a complementary way to study the galactic environment. The actual cosmic rays experiments, for instance PAMELA and HEAT, have presented ve…
Galactic secondary positron flux at the Earth
T. Delahaye, F. Donato, N. Fornengo +5
Secondary positrons are produced by spallation of cosmic rays within the interstellar gas. Measurements have been typically expressed in terms of the positron fraction, which exhib…
Positrons from dark matter annihilation in the galactic halo: theoretical uncertainties
T. Delahaye, R. Lineros, F. Donato +2
Indirect detection signals from dark matter annihilation are studied in the positron channel. We discuss in detail the positron propagation inside the galactic medium: we present n…
