1.5 Direct Detection
- Ian Dell'Antonio
The interaction rate of hypothesized dark matter particles in an Earth bound detector is expected to undergo an annual modulation due to the planet’s orbital motion. The DAMA experiment has observed such a modulation with high significance in an array of scintillating NaI(Tl) crystals, however this results demands a model independent verification.

One of the pillars of the standard cosmological model is the undisputed existence of a relic cosmic neutrino background (CNB) that still need to be probed. Recently a new window to the direct detection of CNB has been opened with the proposal of the PTOLEMY experiment, with a prototype detector ready to be tested at an Underground site, likely the Gran Sasso Laboratory in Italy. Given the...
We present the HeRALD detector concept, a staged path to meV nuclear recoil thresholds. The proposal centers on a 4He target at mK temperatures, which allows long-range ballistic propagation of the superfluid’s phonon and roton excitions. On reaching a liquid-vacuum interface, such kinetic excitations liberate 4He atoms via a one-to-one process, and this signal channel of liberated atoms is...
The ANAIS (Annual modulation with NaI(Tl) Scintillators) experiment aims at the confirmation or refutation of the DAMA/LIBRA positive annual modulation signal in the low-energy detection rate using the same target and technique at the Canfranc Underground Laboratory (LSC) in Spain. Several 12.5 kg NaI(Tl) modules produced by Alpha Spectra Inc. have been operated in Canfranc during the last...
Various cosmological and astrophysical observations strongly support the existence of the Dark Matter (DM) with an abundance of ≈ 27%. Recent theoretical work has highlighted the motivations for sub-GeV dark matter candidates that interact with ordinary matter through new light mediator particles, called "vector portal" model. Recently, a great deal of interest has been paid to the...
