Dark Matter Particles in the Galactic Halo

Understand

The DAMA/LIBRA-phase1 and the former DAMA/NaI data (cumulative exposure 1.33 ton $\times$ yr, corresponding to 14 annual cycles) give evidence at 9.3 $\sigma$ C.L.

• for the presence of Dark Matter (DM) particles in the galactic halo, on the basis of the exploited model independent DM annual modulation signature by using highly radio-pure NaI(Tl) target.
• Results and comparisons will be shortly addressed as well as perspectives of the presently running DAMA/LIBRA-phase2.
• Finally, some arguments arisen in the discussion section of this workshop are mentioned in the Appendix.
