Abstract

DAMA is searching for Dark Matter particles deep underground in the Gran Sasso National Laboratory by using several kinds of scintillators, acting as target-detectors; recent results are here summarized. In particular, the new DAMA/NaI-2 result (14962 kg.day) on the WIMP annual modulation signature achieved by the similar or equal to 100 kg highly radiopure NaI(TI) set-up is summarized. It turns out to be consistent with the DAMA/NaI-1 result (4549 kg.day) and a combined maximum likelihood analysis of the two data sets (19511 kg.day) favours at 99.6% C.L. the hypothesis of presence of an annual modulation of the rate in the energy region of interest for Dark Matter direct detection.
