DAMA/LIBRA-phase1 results and perspectives of the phase2
Abstract
The DAMA/LIBRA experiment — consisting of ∼ 250 kg of highly radio-pure NaI(Tl) — is in data taking in the underground Laboratory of Gran Sasso. The data collected in its first configuration (DAMA/LIBRA—phase1) together with the data of the former DAMA/NaI experiment (∼ 100 kg first generation highly radio-pure NaI(Tl)) correspond to 14 independent annual cycles, for a total exposure of 1.33 ton × yr and point out the presence of DM particle in the Galactic halo at 9.3 σ C.L. on the basis of the model-independent Dark Matter (DM) annual modulation signature. No systematic or side reaction able to mimic the exploited DM signature has been found or suggested by anyone. After an upgrade of the experiment DAMA/LIBRA is now running in its phase2 with increased sensitivity. Here, after briefly reporting the DAMA model independent results, the recent analysis in terms of Mirror Dark Matter candidate will be mentioned.
