Abstract

The DAMA/LIBRA experiment (~ 250 kg sensitive mass composed by highly radio-pure NaI(Tl)) is in data taking in the underground Laboratory of Gran Sasso (LNGS). The data collected in its first 7 annual cycles, corresponding to the so called DAMA/LIBRA–phase1, have been released. Considering also of the former DAMA/NaI experiment (~ 100 kg of highly radio-pure NaI(Tl)) the data of 14 independent annual cycles have been analysed exploiting the model-independent Dark Matter (DM) annual modulation signature (total exposure 1.33 ton × yr). A DM annual modulation effect has been observed at 9.3 σ C.L., thus the presence of DM particles in the galactic halo has been pointed out. No systematic or side reaction able to mimic the observed DM annual modulation has been found or suggested by anyone. At present DAMA/LIBRA is running after an upgrade of the experiment in its phase2 with increased sensitivity.
