Abstract

The DAMA/LIBRA-phase2 experiment (≃ 250 kg highly radiopure NaI(Tl) equipped with new high quantum efficiency photomultipliers) is in progress in the Gran Sasso National Laboratory of the I.N.F.N.. When considering the data collected by DAMA/LIBRA– phase1 and by the former DAMA/NaI experiment (∼ 100 kg of highly radio-pure NaI(Tl)) the data over 14 independent annual cycles, for a total exposure of 1.33 ton × yr, have already been released by exploiting the model-independent Dark Matter (DM) annual modulation signature. Cumulatively a DM annual modulation effect has been observed at 9.3 σ C.L., supporting the presence of DM particles in the galactic halo. No systematic effect or side reaction able to mimic the observed DM annual modulation has been found. Recent corollary analyses in frameworks of Mirror DM candidates and R&D efforts for a possible future DAMA/LIBRA-phase3 are mentioned.
