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 paper, the scaling of the central density ρ(0) at energies up to 900 GeV has been studied and a new form of central region scaling involving the densityρn(0)/ρ(0), expressed as a function ofz=n/〈n〉 is found.

TL;DR: In this article, the authors used the NMSU-WIZARD/CAPRICE94 balloon-borne magnet spectrometer equipped with a solid radiator Ring Imaging Cerenkov (RICH) detector, a time-of-ight system, a tracking device consisting of drift chambers and multiwire proportional chambers, and a silicon-tungsten calorimeter.

TL;DR: The first time a ring-imaging Cerenkov detector was used together with an imaging calorimeter in a balloon-borne experiment was reported in this paper, where 516,463 hydrogen and 32,457 helium nuclei were identi-ed in the rigidity range 0.4 to 200 GV and 1.2 to 4.2 GV, respectively.
