Abstract:

The search for Weakly Interacting Massive Particles (WIMPs), the leading dark matter candidate, is now in decisive phase. Despite lack of evidence for WIMPs in direct searches and in LHC results, a large range of supersymmetric models predicting their existence remains fully consistent with all experimental data. The DEAP-3600 experiment, located at SNOLAB, is currently entering commissioning phase. It is a single-phase detector, which searches for WIMP interactions with 1-tonne fiducial mass of liquid argon target. The sensitivity of DEAP-3600 will exceed current searches by one order of magnitude, offering a real discovery potential. The single-phase liquid argon approach is easily scalable to very large detector masses and liquid argon is a superior target for heavy WIMPs, favored by the existing data. This talk will present an overview of dark matter searches, status of the DEAP-3600 project and plans for DEAP-50T, the next generation 50-tonne liquid argon detector, which will allow full exploration of the allowed parameter space of the leading Standard Model extensions.
