Left panel: The PAMELA positron fraction
(e+/(e++e-)) [1] compared with other
experimental data [13 - 20] and with predictions of a secondary
production model (solid line) [21].
Right panel: The PAMELA electron (e-) spectrum [3] compared with recent electron and electron plus positron (e++e-) data [17, 22 - 30]. |

The antiproton stectrum (left) and antiproton-to-proton flux ratio (right) measured by PAMELA [2], compared with data from other contemporary experiments [4 - 9] and theoretical calculations for purely secondary production of antiprotons in the Galaxy [10 - 12]. |
