TL;DR
The DAMA/LIBRA experiment provides strong, model-independent evidence for dark matter particles in the galactic halo through annual modulation detection, confirming previous results with high statistical significance.
Contribution
This paper reports the latest results from DAMA/LIBRA, confirming dark matter detection with improved data and emphasizing the robustness of the annual modulation signature.
Findings
8.2 sigma confidence level detection
Confirmation of dark matter annual modulation
Supports previous DAMA/NaI results
Abstract
The DAMA/LIBRA set-up (about 250 kg highly radiopure NaI(Tl) sensitive mass) is running at the Gran Sasso National Laboratory of the I.N.F.N.. The first DAMA/LIBRA results confirm the evidence for the presence of a Dark Matter particle component in the galactic halo, as pointed out by the former DAMA/NaI set-up; cumulatively the data support such evidence at 8.2 sigma C.L. and satisfy all the many peculiarities of the Dark Matter annual modulation signature. The main aspects and prospects of this model independent experimental approach will be outlined.
