5 Closing in on the velocity distribution of Dark Matter with direct detection and neutrino telescopes

The next generation of direct detection experiments not only will allow the reconstruction of the Particle Physics properties of Dark Matter (i.e. its mass and scattering cross section), but also the determination of its local velocity distribution. However, this measurement is hinder by the fact that direct detection experiments, being sensitive only above some energy threshold, do not probe down to very low velocities. I am going to show you how this problem can be solved by including the information provided by a (simulated) detection of neutrinos from the Sun. The complementary nature of such a signal will significantly improve the precision in the simultaneous reconstruction of the Dark Mass mass, cross section and velocity distribution.

Speaker: Dr Mattia Fornasa (University of Nottingham)

7 Recent progress with the DEAP-3600 Dark Matter experiment

DEAP-3600 is a single phase liquid argon (LAr) dark matter experiment. It is located 2 km underground at SNOLAB, in Sudbury, Ontario. The detector has 1 tonne fiducial mass target of LAr. Construction of DEAP-3600 is nearly complete and commissioning will start in January 2015. The target sensitivity to spin-independent scattering of 100 GeV WIMPs is 10−46 cm2 which improves the current limits by one order of magnitude. The DEAP- 3600 background target is 0.6 background events in the WIMP region of interest in 3 tonne-years from all sources. This is achieved by selecting ultra low radioactive materials, sanding DEAP-3600 acrylic vessel and developing external calibration sources and deployment systems. The β/γ backgrounds are mitigated by LAr excellent pulse shape discrimination. This talk will present an overview and status of the experiment.
