XENONnT is the follow-up to the XENON1T experiment aming for the direct detection of dark matter using a liquid xenon (LXe) time projection chamber (TPC). The detector, operated at Laboratori Nazionali del Gran Sasso (LNGS) in Italy, features a total LXe mass of 8.5 tonnes of which about 6 tonnes are active. XENONnT has completed its first science run and is currently taking data for the...
Unveiling the nature of dark matter is one of the main goals of modern particle physics. Dark matter direct detection experiments aim at solving the problem by measuring tiny energies deposited inside the detector by dark matter particles interacting with the target materials. Several techniques have been developed to explore the full parameter space of cross-sections and dark matter masses....
I will discuss some possible ways of looking for sub-MeV dark matter using the emission of collective excitations in different media. In particular, I will discuss the possibility of probing spin-independent interactions using superfluid He-4, and spin-dependent ones using antiferromagnets (specifically, NiO and MnF2).
In doing that, I will employ a new theoretical tool, very familiar to high...
In the last decades, the existance of Dark Matter (DM) has become well established, even though its nature is still elusive and unknown. The majority of the experiments searching for a direct signature of DM look at the energy of nuclear recoils induced by scattering with DM candidates. However, the motion of the Earth in the Galaxy produces an apparent wind of DM particles coming from the...
Primordial Black Holes are hypothetical Black Holes formed in the very early universe and are potential Dark Matter Candidates. Focusing on the Primordial Black Holes mass range [$5\cdot10^{14}$−$1\cdot10^{17}$] g, we point out that their evaporation can produce detectable signals in existing experiments. First of all, we study neutrinos emitted by PBHs evaporation. They can interact through...
