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). Its first phase (DAMA/LIBRA-phase1) and the former DAMA/NaI experiment (∼ 100 kg of highly radio-pure NaI(Tl)) collected data for 14 independent annual cycles, 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., supporting the presence of DM particles in the galactic halo. No systematic or side reaction able to mimic the observed DM annual modulation has been found or suggested by anyone. Recent analyses on possible diurnal effects, on the Earth shadowing effect and on possible interpretation in terms of Asymmetric Mirror DM will be mentioned. At present DAMA/LIBRA is running in its phase2 with increased sensitivity.

“…The annual modulation signature is very distinctive as we have already pointed out [4,5,6,7,8,9,10,11]. In fact, a WIMP-induced seasonal effect must simultaneously satisfy all the following requirements: the rate must contain a component modulated according to a cosine function (1) with one year period (2) and a phase that peaks around ≃ 2 nd June (3); this modulation must be found in a well-defined low energy range, where WIMP induced recoils can be present (4); it must apply to those events in which just one detector of many actually "fires", since the WIMP multi-scattering probability is negligible (5); the modulation amplitude in the region of maximal sensitivity must be < ∼ 7% (6).…”

“…DAMA is devoted to the search for rare processes (such as WIMPs direct detection, ββ processes, charge-non-conserving processes, Pauli exclusion principle violating processes, nucleon instability, solar axions and exotics [1,2,3,4,5,6,7,8,9,10,11,12]) by developing and using low radioactive scintillators. The main experimental setups, which are running at present, are: the ≃ 100 kg NaI(Tl) set-up, the ≃ 6.5 kg liquid Xenon (LXe) set-up and the so-called "R&D" apparatus.…”

Abstract. DAMA is searching for rare processes by developing and using several kinds of radiopure scintillators: in particular, NaI(Tl), liquid Xenon and CaF2(Eu). Here only the results released so far on the WIMP annual modulation signature are summarized and compared with results from other experiments, including the recent re-analysis of CDMS-I data. Next perspectives are also shortly addressed.

Abstract. The DAMA/LIBRA experiment, running at the Gran Sasso National Laboratory of the I.N.F.N. in Italy, has a sensitive mass of about 250 kg highly radiopure NaI(Tl). It is mainly devoted to the investigation of Dark Matter (DM) particles in the Galactic halo by exploiting the model independent DM annual modulation signature. The present DAMA/LIBRA experiment and the former DAMA/NaI one (the first generation experiment having an exposed mass of about 100 kg) have released so far results corresponding to a total exposure of 1.17 ton × yr over 13 annual cycles. They provide a model independent evidence of the presence of DM particles in the galactic halo at 8.9 σ C.L. on the basis of the investigated DM signature. The data of another annual cycle in the same DAMA/LIBRA running conditions are at hand. After the replacement at the end of 2012 of all the photomultipliers (PMTs) with new ones, having higher quantum efficiency, DAMA/LIBRA has entered to its phase 2; such a replacements allowed the lowering of the software energy threshold of the experiment in the present data taking. A short summary of the obtained results is presented and future perspectives of the experiment mentioned.
