Scientific paper

We estimate the amount of antiprotons and positrons in cosmic rays due to neutralino annihilations in the galactic halo assuming that dark matter tends to cluster and that these clusters are not disturbed by tidal forces. We find that, assuming neutralinos annihilate mostly to gauge bosons, the amount of antiprotons should exceed the number seen at BESS, whereas the increase in positron flux is below the present detection threshold.
