摘要The diffuse Galactic gamma-rays from EGRET observation shows excesses above 1 GeV in comparison with the expectations from conventional Galactic cosmic ray (CR) propagation model. In the work we try to solve the "GeV excess" problem by dark matter (DM) annihilation in the frame of supersymmetry (SUSY). Compared with previous works, there are three aspects improved in this work: first, the direction-independent "boost factor" for diffuse gamma-rays from dark matter annihilation (DMA) is naturally reproduced by taking the DM substructures into account; second, there is no need for renormalization of the diffuse gamma-ray background produced by CRs; last but not the least, in this work our new propagation model can give consistent results of both diffuse gamma-rays and antiprotons, by directly adding the signals from DMA to the diffuse gamma-ray background. This is a self-consistent model among several possible scenarios at present. and can be tested or optimized by the forthcoming experiments such as GLAST, PAMELA and AMS02. (C) 2008 Elsevier B.V.
