Abstract
The main aim of the' 100 kg highly radiopure NaI(Tl) set-up of the DAMA project (DAMA/NaI) has been the exploitation of the model independent WIMP annual modulation signature. The total exposure (107731 kg x day), collected during seven annual cycles, has given a model independent evidence for the presence ofa Dark Matter particle component in the galactic halo at 6.3σ C.L.; this main result is summarised here. Some of the many possible corollary model dependent quests for the candidate particleare also mentioned. At present, after about fi ve years of new developments, a second generation lowbackground set-up (DAMA/LIBRA with a mass of about 250 kg NaI(Tl)) was built and is taking data since March 2003. New R&D efforts toward a possible NaI(Tl) ton set-up, we proposed in 1996, have been funded and started in 2003.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
