Studies of cosmic antiparticles with PAMELA

Mark Pearce (Dept. of Physics, KTH, Stockholm)


The PAMELA satellite experiment was launched into low earth orbit on June 15th 2006. The combination of a permanent magnet silicon strip spectrometer, and a silicon-tungsten imaging calorimeter allows precision studies of the charged cosmic radiation to be conducted over a wide energy range (~100 MeV – ~200 GeV). A primary scientific goal is to search for dark matter particle annihilations by measuring the energy spectra of cosmic ray antiparticles. Recent results from the PAMELA experiment will be reviewed with a particular focus on cosmic ray antiprotons and positrons.
