Abstract:
The nature of dark matter remains unknown and its origin is currently one of the most important questions in physics. In particular direct searches for WIMP dark matter particle interactions with ordinary matter are carried out with large detectors located in underground laboratories to suppress the background of cosmic rays. One of the currently most promising detection technologies is based on the use of a large mass of liquid argon or xenon as a target in the detector.
In this talk, I will discuss the status and plans for dark matter searches with detectors based on liquid argon. I will present the currently operating DEAP-3600 experiment (at SNOLAB, Canada) and introduce the DarkSide-20k detector (under construction at the Gran Sasso laboratory, Italy) and in particular the design of its neutron veto.
