Description
Dark matter remains one of the most compelling open questions in fundamental physics. While experimental efforts continue to improve in sensitivity, the observation of a simple excess above background would not be sufficient to claim discovery or determine the origin of a potential signal. Characteristic signatures are essential to discriminate between dark matter scenarios.
Among the most motivated sources are particles from the Galactic halo and, in certain models, the Sun. The annual modulation induced by the Earth’s motion through the halo provides a distinctive signature, with an expected amplitude of only a few percent of the total event rate. Exploiting this feature requires both excellent spectral performance and long-term stability.
Next-generation cryogenic observatories such as RES-NOVA offer ultra-low energy thresholds and outstanding energy resolution, enabling precision studies of rare-event spectra. This contribution explores the interplay between energy resolution and temporal modulation sensitivity in underground cryogenic detectors based on archaeological lead, evaluating their potential to probe dark matter signals through combined spectral and time-dependent analyses.
