DARWIN: the ultimate dark matter detector — •Darryl Masson — Universität Freiburg

As dark matter detection experiments continue to push to ever-greater sensitivities, new experiments are devised to glimpse the elusive first signal. The DARWIN project, featuring a 40 tonne liquid xenon target, will attempt to measure WIMP-nucleon scattering cross sections down to ∼10⁻⁴⁹ cm². Additionally, DARWIN should be able to probe the neutrino mass hierarchy via measurements of the half-life of ¹³⁶Xe 0νββ-decay. Other potential science channels include measurements of galactic axions and axion-like particles coupling to electrons and some neutrino interaction channels, such as solar neutrinos via elastic scattering on electrons and galactic supernovae neutrinos via coherent neutrino-nucleus scattering. The current status of the DARWIN project will be presented along with sensitivity projections for a variety of science channels.
