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.
