Weak Interactions

We search for the existence of Dark Matter: Weakly Interacting Massive Particles (WIMP) are thought to be the cold, dark relics of the Big Bang. The DEAP (Dark matter Experiment with Argon and Pulse-shape-discrimination) and CLEAN (Cryogenic Low Energy Astrophysics with Neon) Experiments utilize liquid Argon and Neon in a sensitive search for WIMP dark matter. The MAJORANA Experiment studies neutrinoless double beta decay with an effective Majorana-neutrino mass sensitivity below 50 MeV in order to characterize the Majorana nature of the neutrino, the Majorana mass spectrum, and the absolute mass scale.
