Abstract content

Indirect detection signals from dark matter annihilation are studied in the positron channel. We discuss in detail the positron galactic production spectra and their propagation inside the galactic medium. Predictions for current and upcoming detectors are provided for neutralino dark matter in a variety of supersymmetric schemes. Correlations with other indirect detection signals are discussed in view of a complete multimessenger study of the dark matter problem.
