DAMA is an observatory for rare processes and it is operative deep underground at the Gran Sasso National Laboratory of the INFN. Several low background setups have been realized and many rare processes have been investigated. In particular, the DAMA/Nal setup (similar or equal to 100 kg of highly radiopure NaI(Tl)) has effectively investigated the model-independent annual modulation signature over seven annual cycles (total exposure of 107 731 kg day), obtaining 6.3 sigma C.L. model-independent evidence for the presence of a dark matter particle component in the galactic halo. Some of the many possible corollary model-dependent quests for the candidate particle have been investigated and others are in progress. At present, the second generation DAMA/LIBRA setup (similar or equal to 250 kg of highly radiopure NaI(T1)) is in data taking deep underground.

Abstract
DAMA is an observatory for rare processes and it is operative deep underground at the Gran Sasso National Laboratory of the INFN. Several low background setups have been realized and many rare processes have been investigated. In particular, the DAMA/Nal setup (similar or equal to 100 kg of highly radiopure NaI(Tl)) has effectively investigated the model-independent annual modulation signature over seven annual cycles (total exposure of 107 731 kg day), obtaining 6.3 sigma C.L. model-independent evidence for the presence of a dark matter particle component in the galactic halo. Some of the many possible corollary model-dependent quests for the candidate particle have been investigated and others are in progress. At present, the second generation DAMA/LIBRA setup (similar or equal to 250 kg of highly radiopure NaI(T1)) is in data taking deep underground.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
