1 Silicon Detectors for the Search of Cosmic Antimatter and Dark Matter Piergiorgio Picozza INFN and University of Rome Tor Vergata From e + /e - Colliders to High Energy Astrophysics Trieste, September 7, 2010
2 Astrophysics and Cosmology compelling Issues Apparent absence of cosmological Antimatter Nature of the Dark Matter that pervades the Universe
3 Search for the existence of Antimatter in the Universe PAMELA AMS in Space AMS Accelerators The Big Bang origin of the Universe requires matter and antimatter to be equally abundant at the very hot beginning
4 Gamma Evidence for Cosmic Antimatter? Steigman 1976, De Rujula 1996, Dolgov 2007 Osservation in the 100 MeV gamma range Leading process: p p 0 + Other processes: p p + μ + e + γ 1-10 MeV e + e - γ γ MeV
5 Antimatter Direct research Observation of cosmic radiation hold out the possibility of directly observing a particle of antimatter which has escaped as a cosmic ray from a distant antigalaxy, traversed intergalactic space filled by turbulent magnetic field, entered the Milky Way against the galactic wind and found its way to the Earth. Streitmatter, R. E., 24 th ICRC, Rome, Italy, 1995 Nuovo Cimento, 19, 835 (1996) High energy particle or antinuclei
