Antimatter research in space [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2003
Two of the most compelling issues facing astrophysics and cosmology today are to understand the nature of the dark matter that pervades the universe and to understand the apparent absence of cosmological antimatter. For both issues, sensitive measurements of cosmic-ray antiprotons and positrons, in a wide energy range, are crucial.
