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.
