The Annual Modulation Signature for Dark Matter: DAMA/LIBRA-Phase1 Results and Perspectives
Figure 6
contours in the plane (a) and in the plane (b) for the (2–6) keV and (6–14) keV energy intervals. The contours have been obtained by the maximum likelihood method, considering the cumulative exposure of DAMA/NaI and DAMA/LIBRA-phase1. A modulation amplitude is present in the lower energy intervals and the phase agrees with that expected for DM induced signals. See text.
