Abstract
The first DAMA/LIBRA-phase2 model-independent results (exposure: 1.13, and software energy threshold at 1 keV). They further confirm - with high confidence level - the evidence already observed by DAMA/NaI and DAMA/LIBRA-phase1 on the basis of the exploited model-independent dark matter (DM) annual modulation signature. The total exposure of the three experiments above the 2 keV software energy threshold is 2.46. Here, several DM candidate particles and related scenarios are analyzed including the latest results. Thanks to the increased exposure and to the lower software energy threshold, corollary model-dependent analyses permit to significantly restrict the allowed regions for the parameters spaces of various dark matter candidates and astrophysical, particle and nuclear physics scenarios.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
