Description

ANAIS (annual modulation with NaI Scintillators) is a dark matter direct detection experiment located at the Canfranc Underground Laboratory (LSC, Spain). Its main goal is to proof or refute in a model independent way the DAMA/LIBRA positive result: an annual modulation in the low-energy detection rate compatible with the expected signal induced by WIMPs in the galactic halo. This signal, observed during more than 20 years, is in strong tension with the negative results of other very sensitive experiments, but a direct comparison using the same target material (NaI(Tl)) is still lacking. ANAIS-112, consisting of 112.5 kg of NaI(Tl) scintillators, was installed at the LSC in August 2017 and to the date it has accumulated more than 1.5 y of data. In this talk we will present the annual modulation analysis corresponding to an exposure of 157.55 kgxy and the ANAIS-112 projected sensitivity for the scheduled 5 y of operation.
