Descripción
The ANAIS experiment aims to independently verify or refute the
longstanding positive annual modulation signal observed by DAMA/LIBRA
using the same target and technique. While other experiments have ruled
out the parameter region highlighted by DAMA/LIBRA, their results rely
on assumptions on the dark matter particle and its velocity
distribution, as they utilize different target materials. ANAIS−112,
comprising nine 12.5 kg NaI(Tl) modules arranged in a 3×3 matrix
configuration, has been continuously collecting data at the Canfranc
Underground Laboratory in Spain since August 2017, demonstrating
outstanding performance. Results based on three-year exposure were
consistent with the absence of modulation and not compatible with
DAMA/LIBRA at a sensitivity of almost 3σ confidence level. In this talk, the current state of the experiment and preliminary results with 6 years of data will be discussed. Updated sensitivity projections will be provided, foreseeing a 5σ exclusion of the DAMA/LIBRA signal by late 2025.
