Protons and helium nuclei are the most abundant components of cosmic radiation. Precise measurements their fluxes needed to understand acceleration subsequent propagation rays in our Galaxy. We report precision proton spectra rigidity range 1 gigavolt 1.2 teravolts performed by satellite-borne experiment PAMELA (payload for antimatter matter exploration light-nuclei astrophysics). find that spectral shapes these two species different cannot be described well a single power law.

The satellite-borne experiment PAMELA has been used to make a new measurement of the cosmic-ray antiproton flux and antiproton-to-proton ratio which extends previously published measurements down 60 MeV up 180 GeV in kinetic energy. During 850 days data acquisition approximately 1500 antiprotons were observed. are consistent with purely secondary production Galaxy. More precise models required for complete interpretation results.
A new measurement of the cosmic-ray antiproton-to-proton flux ratio between 1 and 100 GeV is presented. The results were obtained with PAMELA experiment, which was launched into low-Earth orbit on-board Resurs-DK1 satellite on June 15th 2006.

The energy spectra of galactic cosmic rays carry fundamental information regarding their origin and propagation. These spectra, when measured near Earth, are significantly affected by the solar magnetic field. A comprehensive description radiation must therefore include transport modulation inside heliosphere. During end last decade Sun underwent a peculiarly long quiet phase well suited to study processes. In this paper we present proton from July 2006 December 2009 PAMELA. large collected...

Precision measurements of the electron component in cosmic radiation provide important information about origin and propagation rays Galaxy not accessible from study cosmic-ray nuclear components due to their differing diffusion energy-loss processes. However, when measured near Earth, effects modulation galactic heliosphere, particularly significant for energies up at least 30 GeV, must be properly taken into account. In this paper (e^-) spectra by PAMELA down 70 MeV July 2006 December 2009...
The propagation of cosmic rays inside our galaxy plays a fundamental role in shaping their injection spectra into those observed at Earth. One the best tools to investigate this issue is ratio fluxes for secondary and primary species. boron-to-carbon (B/C) ratio, particular, sensitive probe mechanisms. This paper presents new measurements absolute boron carbon nuclei, as well B/C from PAMELA space experiment. results span range 0.44 - 129 GeV/n kinetic energy data taken period July 2006 March 2008.
Precise measurements of the time-dependent intensity low energy ($<50$ GeV) galactic cosmic rays are fundamental to test and improve models which describe their propagation inside heliosphere. Especially, data spanning different solar activity periods, i.e. from minimum maximum, needed achieve comprehensive understanding such physical phenomenon. The phase between 23$^{rd}$ 24$^{th}$ cycles was peculiarly long, extending up beginning 2010 followed by maximum phase, reached during early 2014....

ABSTRACT Forty years ago Witten suggested that dark matter could be composed of macroscopic clusters strange quark matter. This idea was very popular for several years, but it dropped out fashion once lattice quantum chromodynamics calculations indicated the confinement/deconfinement transition, at small baryonic chemical potential, is not first order, which seemed to a crucial requirement in order produce large quarks. Here, we revisit conditions under strangelets can produced Early...
