The dark matter community is increasingly focused on developing advanced detector technologies to detect a wide range of dark matter candidates, complementing planned searches for weakly interacting massive particles (WIMPs).
The DarkSide-50 detector at LNGS, Italy, has shown the ability to detect low-mass WIMPs (<10 GeV/c2) interacting with nuclei and electron-scattering DM down to 20 MeV/c2. I'll present new DarkSide-50 results for low-mass DM and ongoing efforts for the DarkSide-LowMass experiment. Additionally, I'll discuss our work on low-energy nuclear recoil calibration and our exploration of applying LAr technology to PET scanners for medical imaging.
