Paolo Ciarcelluti (Liege, Belgium):

"Astrophysics of mirror dark matter"

Abstract. Mirror matter is a self-collisional dark matter candidate. If exact mirror parity is a conserved symmetry of the nature, there could exist a parallel hidden (mirror) sector of the Universe which has the same kind of particles and the same physical laws of our (visible) sector. The two sectors interact each other predominantly via gravity, therefore mirror matter is naturally "dark". This candidate is so far compatible with all the experiments, and in particular it can explain the recent DAMA/LIBRA results. The most promising way to test this dark matter candidate is to look at its astrophysical signatures, as Big Bang nucleosynthesis (BBN), primordial structure formation and evolution, cosmic microwave background (CMB) and large scale structure power spectra, dark stellar structures (microlensing events). In this talk I review the research in all these topics.
