Dark Matter implications of DAMA/LIBRA-phase2 results

Understand

Recently, the DAMA/LIBRA collaboration released updated results from their search for the annual modulation signal from Dark Matter (DM) scattering in the detector.

• Besides approximately doubling the exposure of the DAMA/LIBRA data set, the updated photomultiplier tubes of the experiment allow a lower recoil energy threshold of 1\,keV electron equivalent compared to the previous threshold of 2 keV electron equivalent.
• We study the compatibility of the observed modulation signal with DM scattering.
• Due to a conspiracy of multiple effects, the new data at low recoil energies is very powerful for testing the DM hypothesis.
