SUMMARY:Search for Dark Matter with Liquid Argon Detectors - Marcin Kuzniak
  (Carleton)
DESCRIPTION:Although the existence of Dark Matter is well established based
  on astronomical observations\, its nature remains one of the most pressin
 g and exciting questions in physics\, with Weakly Interacting Massive Part
 icles (WIMPs) still among the top Dark Matter candidates.  This talk will 
 discuss WIMP detection based on liquid argon\, which is complementary and 
 has advantages over more established xenon technology (currently dominatin
 g the field). I will describe the DEAP-3600 detector\, which searches for 
 dark matter particle interactions with 3.6 tonnes of liquid argon containe
 d in an ultrapure acrylic vessel viewed by 255 photomultiplier tubes. It i
 s located 2 km underground at SNOLAB\, in Sudbury\, Ontario\, and currentl
 y taking data\, aiming to reach a competitive sensitivity (or discover WIM
 Ps) after 3 years of running.  I will also discuss DarkSide-20k\, a larger
  20 ton detector planned for the future\, as well as prospects for a globa
 l collaborative effort to build a multi-hundred ton scale instrument\, cap
 able of reaching the ultimate sensitivity available to WIMP searches.
