Oral presentation in parallel session Dark matter DM13: WIMP Dark Matter II

Speaker

Dr Shawn Westerdale (Carleton University)

Description

DEAP-3600 is a dark matter direct detection experiment operating 2 km underground at SNOLAB (Sudbury, Canada). This single-phase detector consists of 3.3 tonnes of liquid argon (LAr), viewed by an array of 255 photomultiplier tubes through 50 cm of acrylic. The collaboration has recently released dark matter search results from the first year of running (November 2016 to October 2017), with a total live time of 231 days. This talk will detail the analysis underlying these results, including the development of a detailed background model, which constitute the most sensitive search performed with a LAr target for WIMPs with a mass greater than 30 GeV.
