dc.descriptionWe use the constraints on the diffusion parameters as obtained with stable nuclei to calculate the cosmic antiproton flux from annihilating relic neutralinos. We discuss the relevance of each characteristic parameter, describing our two dimension diffusion model, on the flux of antiprotons produced in the dark halo of our Galaxy. We estimate a two orders of magnitude uncertainty on the flux due to the unknowledge of the propagation parameters. A conservative and systematic evaluation of the flux in the supersymmetric parameter space is done in order to exclude configurations providing a total (secondary plus primary) flux in excess with observations. We also study the effect on the flux induced by modifications in the distribution of cold dark matter in the Galaxy.
