Direct experimimental evidence of DM particles in the galactic halo (6.3 σ C.L.)
The DAMA/NaI experiment has investigated various approaches for DM and several other rare processes.
It was, however, proposed, designed and realized having the main aim to investigate with suitable exposure, sensitivity and running conditions
the model independent annual modulation signature able to directly test the presence of Dark Matter particles
in the galactic halo.
Some of the many possible corollary investigations on the nature of the candidate
have also been carried out by the collaboration
with time passing and by some other authors; others are in progress.
