Description
The ANAIS experiment aims to verify or refute in a model independent way with a high statistical significance the longstanding positive annual modulation signal observed by DAMA/LIBRA. For this goal, ANAIS experiment uses the same target, NaI(Tl), and technique, the analysis of the annual modulation in the scintillation signal observed at very low energy. ANAIS−112 consists of nine modules, 12.5 kg each, of NaI(Tl) arranged in a 3×3 configuration, plus a blank module without NaI(Tl) crystal. ANAIS-112 has been continuously collecting data at the Canfranc Underground Laboratory in Spain since August 2017, demonstrating outstanding performance. Updated results with six-year exposure will be presented: they are consistent with the absence of modulation and incompatible with the DAMA/LIBRA result with a sensitivity above 4σ C.L. Systematics affecting this test will be analysed and discussed. Finally, updated sensitivity projections will be provided, pointing at a 5σ exclusion of the DAMA/LIBRA signal with the data accumulated by the end of 2025.
