Signals from the Universe: from DAMA/NaI to DAMA/LIBRA

Antonella Incicchitti (INFN, Rome)

The highly radiopureabout 250 kg NaI(Tl) DAMA/LIBRA set-up is running at the GranSassoNational Laboratory of the I.N.F.N.. Results exploiting the model independent annual modulation signature for Dark Matter particles in the galactic halo are presented (exposure of 0.53 ton x yr). The DAMA/LIBRA data confirm the evidence for the presence of Dark Matter particles in the galactic halo as observed by theformer DAMA/NaIexperiment. The combined analysis of the data of the two experiments (total exposure 0.82 ton x yr) gives a C.L. at 8.2 sigma.
