Description

The fluxes and flux ratios of charged elementary particles in cosmic rays are presented in the absolute rigidity range from 1 to 1000 GV. In the absolute rigidity range ∼60 to ∼500 GV, the antiproton and proton are found to have nearly identical rigidity dependence. Below 60 GV, the antiproton-to-proton, ratio reaches a maximum. Future perspectives for antiproton flux measurement will also be discussed.
