Query: Indirect Evidence for Neutralinos as Dark Matter   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.
