“ANTIPARTICLES (e+, p−, D−, anti-3He) constitute a golden channel for this search, since the rare antiparticle component of DM annihilation/decay products, would give rise to an observable excess on these fluxes with respect to the tiny standard astro-physical expectations, not influenced by the otherwise large background of standard CRs.” (DM = dark matter; CR = cosmic ray).
