Antiprotons in cosmic rays from neutralino annihilation

We calculate the cosmic antiproton flux from annihilating relic neutralinos using the constraints on the diffusion parameters, as obtained with stable nuclei analysis. The propagated flux is affected by an uncertainty rising two orders of magnitude because of the ignorance of the propagation parameters. A conservative and systematic evaluation of the flux in the supersymmetric parameter space is performed, with the search for those configurations potentially providing a total (secondary plus primary) flux in excess with observations.
