“Searching for dark matter with liquid argon”

The DarkSide collaboration has undertaken a staged program using argon time projection chambers (TPCs) to search for dark matter. I will introduce DarkSide-50, a 50 kg dual-phase argon TPC that has been operating since mid-2015 at LNGS, and present recent results from this detector. Then I will discuss the implications of these results for a next-generation experiment, DarkSide-20k, a more than 20 tonne fiducial mass TPC equipped with SiPM-based photosensors.
