| 英文摘要 | In this paper we calculate the galactic positron flux from dark matter annihilation in the framework of supersymmetry, taking the enhancement of the flux by the existence of dark matter substructures into account. The propagation of positrons in the galactic magnetic field is solved in a realistic numerical model GALPROP. The secondary positron flux is recalculated in the GALPROP model. The total positron flux from secondary products and dark matter annihilation can fit the HEAT data well when taking a cuspy density profile of the substructures. |
