Direct detection of dark matter particles

In this conference the model-independent result on the presence of dark-matter particles in the galactic halo obtained over seven annual cycles by the 100 kg highly radiopure NaI(Tl) DAMA/NaI has been presented and several corollary investigations have also been discussed. More recently the model-independent result obtained over the first four annual cycles by the second generation 250 kg highly radiopure NaI(Tl) DAMA/LIBRA set-up at the Gran Sasso National Laboratory of the INFN has also been released. Both the experiments have the unique feature to effectively investigate the presence of dark-matter particles in the galactic halo by exploiting the model-independent annual modulation signature. The data collected by the two experiments over eleven annual cycles for a total exposure of 0.82 ton × y have pointed out at 8.2σ CL a positive result; several corollary model-dependent quests for the candidate particle(s) and related astrophysical, nuclear and particle physics scenarios are under updating. The future experimental activity can give rise to many new interesting results.
