17 Antiparticles with PAMELA
18 Astrophysics and Cosmology compelling Issues Apparent absence of cosmological Antimatter Nature of the Dark Matter that pervades the Universe
19 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
20 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
21 THE UNIVERSE ENERGY BUDGET

23 Another possible scenario: KK Dark Matter Lightest Kaluza-Klein Particle (LKP): B (1) As in the neutralino case there are 1-loop processes that produces monoenergetic γ γ in the final state. Bosonic Dark Matter: fermionic final states no longer helicity suppressed. e+e - final states directly produced.
24 DM annihilations DM particles are stable. They can annihilate in pairs. Primary annihilation channels Decay Final states σ a = <σv>
