A new measurement of the antiproton-to-proton flux ratio up to 100 GeV in the cosmic radiation
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +50
A new measurement of the cosmic ray antiproton-to-proton flux ratio between 1 and 100 GeV is presented. The results were obtained with the PAMELA experiment, which was launched int…
