The Annual Modulation Signature for Dark Matter: DAMA/LIBRA-Phase1 Results and Perspectives

Figure 3

Experimental single-hit residuals in the (2–6) keV and in the (6–14) keV energy regions for the entire DAMA/LIBRA-phase1 data as if they were collected in a single annual cycle (i.e., binning in the variable time from the Jan 1st of each annual cycle). The data points present the experimental errors as vertical bars and the associated time bin width as horizontal bars. The initial time of the figures is taken at August 7th. A clear modulation satisfying all the peculiarities of the DM annual modulation signature is present in the lowest energy interval with  cpd/kg/keV, while it is absent just above cpd/kg/keV.
