Cosmic ray studies with PAMELA experiment
2011 (English)In: Proceedings of the 14th Lomonosov Conference on Elementary Particle Physics: Particle Physics at the Year of Astronomy: Dedicated to the Late Academician Alexey Sissakian, 2011, 200-206 p.Conference paper (Refereed)
The instrument PAMELA, in orbit since June 15th, 2006 on board of the Russian satellite Resurs DK1, is daily delivering to ground 16 Gigabytes of data. The apparatus is designed to study charged particles in the cosmic radiation, with a particular focus on antiparticles for searching antimatter and signals of dark matter annihilation. A combination of a magnetic spectrometer and different detectors allows antiparticles to be reliably identified from a large background of other charged particles. New results on the antiproton-to-proton and positron-toall electron ratios over a wideenergy range (1-100 GeV) have been obtained from the PAMELA mission. These data are mainly interpreted in terms of dark matter annihilation or pulsar contribution.
