Parallel talks 5: Astro-particle Physics & Cosmology

We propose a UV completion model for pseudo-Nambu-Goldstone dark matter with a hidden U(1) gauge symmetry. Dark matter scattering off nucleons is highly suppressed by the UV scale and direct detection constraints can be easily evaded. The kinetic mixing between the hidden U(1) and the $\mathrm{U(1)_Y}$ gauge fields would lead to dark matter decays. The current bound on the dark matter lifetime...
Located at the Gran Sasso underground laboratories, the XENONnT experiment is a dark matter direct detection experiment that employs a dual-phase liquid xenon time projection chamber with a 5.9-tonne liquid xenon target. Building on the infrastructure developed for XENON1T with several upgrades, the XENONnT experiment is currently acquiring data and pushing the frontiers of astroparticle...
DarkSide-20k represents the next stage of the direct detection dark matter search program based on argon as its target material within the Global Argon Dark Matter Collaboration (GADMC). The experiment is currently under construction at LNGS, Italy. The argon target provides powerful discrimination between the electron (background) and nuclear (signal) recoils in the form of pulse shape...
The search for light dark matter (LDM) particles became possible in recent years mainly thanks to the progress on two different fronts. First, new detection channels were exploited such as the Migdal effect and LDM–electron scattering. Second, new detection techniques were implemented such as the ionization-only channel with a low threshold and argon depleted from the 39Ar β-emitter by...
