|Understanding Cosmic Rays and Searching for Dark Matter with PAMELA|
|Speaker:||Piergiorgio Picozza (University of Rome Tor Vergata)|
|Abstract:||New results on high-energy spectra of cosmic-ray electrons, positrons, protons, antiprotons, helium and light nuclei have been obtained by the PAMELA mission.The instrument PAMELA, in orbit since June 15th, 2006 on board 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.
Data will be discussed in the context of dark matter searching, pulsar contribution, mechanisms of acceleration and propagation of cosmic rays in the Galaxy and solar modulation.|
