Effects of Solar Modulation on the Low-energy Cosmic-ray Antiproton/proton Ratio


We examine the transport of cosmic-ray protons and anitprotons from local interstellar space through the interplanetary medium to Earth and discuss the resulting e†ects on the low-energy antiproton/proton ratio at 1 AU. We Ðnd that the antiproton/proton ratio at energies above D3 GeV is a useful diagnostic of cosmic-ray transport in the Galaxy. However, at… (More)
