TL;DR: It is found that the positron fraction increases sharply over much of that range, in a way that appears to be completely inconsistent with secondary sources, and is concluded that a primary source, be it an astrophysical object or dark matter annihilation, is necessary.

TL;DR: PAMELA data challenge the current paradigm of cosmic-ray acceleration in supernova remnants followed by diffusive propagation in the Galaxy and find that the spectral shapes of these two species are different and cannot be described well by a single power law.

TL;DR: The PAMELA satellite experiment has measured the cosmic-ray positron fraction between 1.5 GeV and 100 GeV, and the need to reliably discriminate between the positron signal and proton background has required the development of an ad hoc analysis procedure.

TL;DR: In this paper, the antiproton spectrum and the ratio of the fluxes of primary cosmic ray antiprotons to protons with energies of 60 MeV to 350 GeV were measured from the data obtained from June 2006 to January 2010 in the PAMELA experiment.
Journal ArticleDOI
Modulation of galactic protons in the heliosphere during the unusual solar minimum of 2006 to 2009
TL;DR: In this paper, the PAMELA cosmic ray detector on-board the Resurs-DK1 satellite was used to determine what mechanisms were mainly responsible for the modulation of protons during this period, and why the observed spectrum for 2009 was the highest ever recorded.
