The low background DAMA/NaI experiment (similar or equal to 100 kg highly radiopure NaI(T1)) at the Gran Sasso National Laboratory of the I.N.F.N. investigated the presence of Dark Matter particle in the galactic halo by exploiting the model independent annual modulation signature. This experiment has collected data over seven annual cycles for a total exposure of more than 10(5) kg x day and has pointed out at 6.3 sigma C.L. a modulation effect satisfying all the many peculiarities of the signature.

Abstract
The low background DAMA/NaI experiment (similar or equal to 100 kg highly radiopure NaI(T1)) at the Gran Sasso National Laboratory of the I.N.F.N. investigated the presence of Dark Matter particle in the galactic halo by exploiting the model independent annual modulation signature. This experiment has collected data over seven annual cycles for a total exposure of more than 10(5) kg x day and has pointed out at 6.3 sigma C.L. a modulation effect satisfying all the many peculiarities of the signature. Several corollary model dependent quests for the candidate particle have also been carried out. At present the second generation DAMA/LIBRA setup (similar or equal to 250 kg highly radiopure NaI(T1)) is in operation. A R&D towards possible 1 ton NaI(T1) set-up is also in progress.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
