The PAMELA experiment is a satellite-borne apparatus designed to study charged particles
in the cosmic radiation with a particular focus on antiparticles. PAMELA is mounted on the …

The data collected by ATIC, PPB-BETS, FERMI-LAT and HESS all indicate that there is an
electron/positron excess in the cosmic ray energy spectrum above~ 100 GeV, although …

Fully updated for the second edition, this book introduces the growing and dynamic field of
particle astrophysics. It provides an overview of high-energy nuclei, photons and neutrinos …

We have made a new calculation of the cosmic-ray secondary positron spectrum using a
diffusive halo model for Galactic cosmic-ray propagation. The code computes self …

The detection of primary cosmic ray electrons with energies above 1 TeV implies the
existence of a nearby, r≤ 100 pc, and relatively young, t≤ 10 5 yr, source (s) of accelerated …

Two measurements of the cosmic-ray positron fraction as a function of energy have been
made using the High-Energy Antimatter Telescope (HEAT) balloon-borne instrument. The …

Aims. This paper gives a description of a new online database and associated online tools
(data selection, data export, plots, etc.) for charged cosmic-ray measurements. The …

Measurements of the energy spectra of negative electrons and positrons have been
performed with the High-Energy Antimatter Telescope (HEAT) in two balloon flights—1994 …

We report on a new measurement of the cosmic-ray electron and positron spectra. The data
were collected by the balloon-borne experiment CAPRICE94, which was flown from Lynn …

If the dark matter in our galactic halo consists of weakly interacting massive particles
(WIMP's) heavier than the W±boson which have a significant annihilation branch into W±and …
