seminario di Giulia D’Imperio “new detectors for dark matter search through modulation and directionality”
Despite representing the majority of the mass of the universe, dark matter (DM) has never been directly observed. The detection strategy of the most sensitive experiments today is to select nuclear recoils induced by the scattering of WIMPs in ton-scale detectors. SABRE and CYGNO experiments plan to use different and complementary approaches to detect DM through, respectively, the annual modulation of experimental rate in NaI(Tl) crystals, and the directionality of low energy nuclear recoils using a gaseous TPC with optical readout. The status and the latest results of SABRE and CYGNO prototypes will be presented, as well as the potential of these techniques to shed light on the DM puzzle.
