We report the main results of a paper where recent data of low-energy cosmic-ray p spectrum have been analyzed in terms of newly calculated fluxes for secondary antiprotons and for a possible contribution of an exotic signal due to neutralino annihilation in the galactic halo. We also present the results of a paper in which we have proved that a sizeable fraction of the supersymmetric neutralino configurations, singled out by the DAMA/NaI data on a possible annual modulation effect in WIMP direct search, may provide detectable cosmic-ray antiproton signals.
