Observation of an anomalous positron abundance in the cosmic radiation
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +48
Positrons are known to be produced in interactions between cosmic-ray nuclei and interstellar matter ("secondary production"). Positrons may, however, also be created by dark matte…
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…

M. Casolino, P. Picozza, F. Altamura +56
PAMELA is a satellite borne experiment designed to study with great accuracy cosmic rays of galactic, solar, and trapped nature in a wide energy range protons: 80 MeV-700 GeV, elec…
