T1-4 Direct Detection of Dark Matter (PPD) | Détection directe de la matière sombre (PPD)
- David Morrissey (TRIUMF)
An overview of dark matter detection in the Milky Way galactic halo will be presented, including constraints and cutting-edge searches for dark matter's interactions with nuclei and electrons. The theory of non-relativistic dark matter interactions, connections with early universe cosmology, and the status of underground dark matter experiments will be addressed, along with some new detection...
Dark matter search results and a detailed background model for DEAP-3600 will be presented. DEAP-3600 is searching for dark matter interactions with a target of liquid argon, shielded from cosmic rays by more than 2 km of rock at SNOLAB in Sudbury, Canada. The spherical detector consists of 3.3 tonnes of liquid argon in a large ultralow-background acrylic cryostat instrumented with 255...
Cosmological and astrophysical observations indicate that the vast majority of the universe’s matter content is made out of dark matter.
Over the past decades, the physics community has largely focused on searching for dark matter within the 10 GeV-1 TeV mass range (WIMPs).
The absence of a discovery has motivated us to broaden our experimental search program and to look for lighter dark...
The PICO collaboration uses bubble chambers to search for dark matter with results leading the world in sensitivity to the direct detection of WIMPs with spin-dependent coupling to protons. PICO recently operated a 32 litre bubble chamber (PICO-60) at the SNOLAB underground laboratory and the next generation experiment is currently taking commissioning data. This new device (PICO-40L) will...
