Experimental observations and theoretical arguments at galactic and larger scales pointed out that a large fraction of the Universe is composed of Dark Matter (DM) particles. This has motivated the pioneer DAMA experimental eﬀorts to investigate the presence of such particles in the galactic halo, by exploiting a model independent signature and very highly radio–pure apparata in deep underground. In this paper, after a short introductory part, the long–standing model–independent annual modulation eﬀect measured by DAMA Collaboration, with various experimental conﬁgurations, is examined. In the energy region between 2 and 6 keV, the data from DAMA/NaI, DAMA/LIBRA–phase1 and DAMA/LIBRA–phase2 (full exposure: 2.46 ton × yr) conﬁrm the evidence of a signal that meets all the several speciﬁc requirements of the exploited model independent DM annual modulation signature, at 12.9 σ C.L.. The DAMA/LIBRA–phase2 conﬁguration, proﬁting from new high quantum eﬃciency photomultipliers, new electronics and other improvements with respect to DAMA/LIBRA–phase1, has also allowed the conﬁrmation of such an evidence down to a software energy threshold of 1 keV. The complexity and the uncertainties of corollary model dependent quests for the DM candidate particle(s) and related scenarios are also addressed at some extent and several of the many possibilities are examined. The eﬀorts towards the new phase3 of the experiment are summarized, showing the strategies and the results obtained with the present developments.
