Abstract

The long-standing model-independent annual modulation effect measured by DAMA deep underground at the Gran Sasso National Laboratory (LNGS) of the I.N.F.N. using different experimental configurations is summarized also including the results of two new annual cycles collected by DAMA/LIBRA-phase2; the total exposure of DAMA/LIBRA-phase2 over 8 annual cycles is 1.53 t yr. The evidence of a signal that meets all the requirements of the model independent dark matter (DM) annual modulation signature is further confirmed at 11.8 sigma C.L. in the energy region (1-6) keV. In the energy region between 2 and 6 keV, where data are also available from DAMA/NaI and DAMA/LIBRA-phase1, the achieved C.L. for the full exposure (2.86 t yr) is 13.7 sigma.
