# ANAIS-112 sensitivity in the search for dark matter annual modulation

## TL;DR

The paper evaluates the ANAIS-112 experiment's potential to independently confirm the dark matter annual modulation signal observed by DAMA/LIBRA using NaI(Tl) detectors over five years.

## Contribution

It provides a model-independent analysis of ANAIS-112's sensitivity and compares its detection prospects with other experiments searching for dark matter modulation signals.

## Key findings

- ANAIS-112 can detect the DAMA/LIBRA modulation at 3σ after 5 years.
- A figure of merit was developed to compare different dark matter detection experiments.
- ANAIS-112's sensitivity supports its role in testing DAMA/LIBRA's results independently.

## Abstract

The annual modulation measured by the DAMA/LIBRA experiment can be explained by the interaction of dark matter WIMPs in NaI(Tl) scintillator detectors. Other experiments, with different targets or techniques, exclude the region of parameters singled out by DAMA/LIBRA, but the comparison of their results relies on several hypotheses regarding the dark matter model. ANAIS-112 is a dark matter search with 112.5 kg of NaI(Tl) scintillators at the Canfranc Underground Laboratory (LSC) to test the DAMA/LIBRA result in a model independent way. We analyze its prospects in terms of the a priori critical and detection limits of the experiment. A simple figure of merit has been obtained to compare the different experiments looking for the annual modulation observed by DAMA/LIBRA. We conclude that after 5 years of measurement, ANAIS-112 can detect the annual modulation in the 3$\sigma$ region compatible with the DAMA/LIBRA result.
