Particle Dark Matter in the galactic halo.

The DAMA/LIBRA-phase1 and the former DAMA/NaI data (cumulative exposure 1.33 ton yr, corresponding to 14 annual cycles) give evidence at 9.3 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 recalled. Recent analyses on possible diurnal effects and on the Earth shadowing effect (the latter holds only for some DM candidates) will be mentioned. The analysis of the time distribution of the low-energy single-hit events in DAMA/LIBRA-phase1 is reported for the first time. Finally, some perspectives of the presently running DAMA/LIBRA-phase2 will be mentioned. [ABSTRACT FROM AUTHOR]
