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: In this article, the absolute fluxes of boron and carbon nuclei as well as the B/C ratio from the PAMELA space experiment were measured for data taken in the period 2006 July to 2008 March.

TL;DR: In this article, the absolute fluxes of boron and carbon nuclei, as well as the B/C ratio, from the PAMELA space experiment were investigated.

TL;DR: In this paper, the preliminary design of the new space gamma-ray telescope GAMMA-400 for the energy range 100 MeV-3 TeV is presented, which is optimized to address a broad range of science topics, such as search for signatures of dark matter, studies of galactic and extragalactic gamma-rays sources, Galactic and extrgalactic diffuse emission, gamma burst, as well as high-precision measurements of spectra of cosmic-ray electrons, positrons, and nuclei.

TL;DR: The existence of a significant flux of antiprotons confined to Earth's magnetosphere has been considered in several theoretical works as discussed by the authors, which constitutes the main source of trapped protons at energies above some tens of MeV.
