Abstract
Arguments on the investigation of the Dark Matter particles in the galactic halo are addressed. Recent results obtained by the DAMA/LIBRA set-up – exploiting the model independent annual modulation signature for Dark Matter (DM) particles – are shortly summarized. In fact, the DAMA project is an observatory for rare processes and it is operative deep underground at the Gran Sasso National Laboratory of the I.N.F.N. Its main apparatus is at present the DAMA/LIBRA set-up, consisting of ≃ 250 kg highly radiopure NaI(Tl) detectors. Its first results confirm those obtained by the former DAMA/NaI, supporting the evidence for Dark Matter presence in the galactic halo at 8.2 σ C.L.; in addition, the cumulative data satisfy all the many peculiarities of the DM annual modulation signature. Future perspectives are also addressed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
