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

Table 1

Best fit values for the (2–6) and (6–14) keV energy intervals (1𝜎 errors) for 𝑆_𝑚 versus 𝑍_𝑚 and 𝑌_𝑚 versus 𝑡^∗, considering the cumulative exposure of DAMA/NaI and DAMA/LIBRA-phase1. See also Figure 6.

𝐸 (keV)	𝑆𝑚 (cpd/kg/keV)	𝑍𝑚 (cpd/kg/keV)	𝑌𝑚 (cpd/kg/keV)	𝑡^∗ (day)
