Résumé : We investigate the prospects for indirect detection of neutralino dark matter in the context of effective supergravity theories derived from the heterotic superstring. These models provide a consistent framework linking fundamental high-energy theory with low energy physics, and a phenomenology in the gaugino and scalar sector, which is considerably different from the commonly discussed case of minimal Supergravity. We show that astrophysical observations, in particular with gamma-ray experiments like GLAST and HESS, will provide significant constraints on combinations of astrophysical and particle physics parameters, and interesting clues on the SUSY breaking mechanism. © 2005 Elsevier B.V.
