Description
DAMA/LIBRA observation of an annual modulation in the detection rate compatible with that expected for dark matter particles from the galactic halo has accumulated evidence for more than twenty years. It is the only hint about a positive identification of the dark matter, but it is in strong tension with the negative results of other very sensitive experiments. However, this comparison is model-dependent. By using the same target material than DAMA/LIBRA experiment, NaI(Tl), such a comparison is (almost) independent in dark matter particle and halo models. ANAIS-112 experiment, using 112.5 kg of NaI(Tl) as target, is taking data at the Canfranc Underground Laboratory in Spain since August 2017. Results corresponding to three-year are compatible with the absence of modulation and in tension with DAMA/LIBRA result. In August 2022, five years of data taking will be completed. Present status of the experiment and prospects to test DAMA/LIBRA beyond three sigma will be reported in this talk together with recent analysis improvements and a discussion on open data strategy and systematics in the comparison of both experiments.
