Abstract

Several of the many proposed Dark Matter candidate particles, already investigated with lower exposure and a higher software energy threshold, are further analyzed including the first DAMA/LIBRA-phase2 data release, with an exposure of 1.13 tyr and a lower software energy threshold (1 keV). The cumulative exposure above 2 keV considering also DAMA/NaI and DAMA/LIBRA-phase1 results is now 2.46 tyr. The analysis permits to constrain the parameters’ space of the considered candidates restricting their values – with respect to previous analyses – thanks to the increase of the exposure and to the lower energy threshold.
