The first DAMA/LIBRA–phase2 model-independent results (exposure: 1.13 ton × yr, and software energy threshold at 1 keV) have recently been released.

Abstract
The first DAMA/LIBRA–phase2 model-independent results (exposure: 1.13 ton × yr, and software energy threshold at 1 keV) have recently been released. 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 above 2 keV of the three experiments is 2.46 ton × yr. Several DM candidate particles and related scenarios have been analyzed including the latest results. These analyses permit to constrain the parameters’ space of the considered candidates in the given scenarios, restricting their values with respect to previous analyses thanks to the increased exposure and to the lower energy threshold.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
