Seminarium "High Energy, Cosmology and Astro-particle Physics (HECA)"

Within the dark matter community, there is increasing interest in developing novel detector technologies with sensitivity to a wide range of dark matter (DM) candidates, complementing the many planned large-exposure searches for weakly interacting massive particles (WIMPs).The results from the DarkSide-50 detector, a dual-phase liquid argon time projection chamber (LAr TPC) located at the Laboratori Nazionali del Gran Sasso (LNGS), Italy, demonstrated the ability to extend the reach of a LAr TPC to WIMPs with masses below 10 GeV/c2 that scatter on nuclei (low-mass WIMPs), and to DM particles that scatter on electrons with masses down to 20 MeV/c2 (electron-scattering DM).I will present new results from DarkSide-50 for low-mass DM and current ongoing effort for a tonne-scale LAr TPC, DarkSide-LowMass experiment, as well as low energy nuclear recoil calibration experiment. I will also present our effort to apply the LAr technology to a medical scanner with Positron Emission Tomography (PET).
