Abstract
From the relic density measurement by WMAP the WIMP annihilation cross section can be determined in a model independent way. If the WIMPS are postulated to be the neutralinos of Supersymmetry, then only a limited region of the supersymmetric parameter space matches this annihilation cross section. It is shown that the resulting positrons, antiprotons and gamma rays from the neutralino annihilation (mainly into b-bbar quark pairs) provide the correct shape and order of magnitude for the missing gamma and hard positron fluxes in the Galactic Models and are consistent with antiproton production.
