Investigations on particle DArk MAtter and other rare processes with highly radiopure scintillators

DAMA is an observatory for rare processes, developing and using highly radiopure scintillators. It has also been a pioneer activity in the direct investigation of Dark Matter (DM) particles in the galactic halo. In particular, the 1st generation DAMA/NaI (~100 kg highly radiopure NaI(Tl)) pointed out over 7 annual cycles (exposure: 0.29 ton x yr) a model independent evidence for the presence of DM particles in the galactic halo with high C.L. The 2nd generation DAMA/LIBRA (~250 kg highly radiopure NaI(Tl)) has confirmed in 2008 this model independent result over 4 annual cycles (exposure: 0.53 ton x yr) also at high C.L.. Further 2 annual cycles have been released in 2010 (cumulative exposure: 0.87 ton x yr). In August 2013 an additional annual cycle has been released, giving the cumulative model independent result of DAMA/LIBRA-phase1 (total exposure: 1.04 ton x yr). The model independent evidence for the presence of DM particles in the galactic halo is 9.3 σ. No systematic or side reaction able to mimic the exploited DM signature (i.e. able to account for the whole measured modulation amplitude and simultaneously account for the many peculiarities of the exploited signature) has been found or suggested by anyone over more than a decade. After the upgrading occurred in fall 2010 the experiment is running in its phase2. In particular, on March 26, 2018 the results obtained with 6 annual cycleas of DAMA/LIBRA-phase2 have been presented at LNGS. The software energy threshold is 1 keV and an additional exposure of 1,13 ton x yr has been released (see download section). In 2021 the results obtained with other 2 annual cycles of DAMA/LIBRA-phase2 have
