A large amount of evidence supports the theory that 25% of the universe is composed of cold dark matter. The XENON project has conducted several experiments using a liquid xenon target in a dual phase time projection chamber (TPC) in an attempt to detect dark matter in the form of Weakly Interacting Massive Particles (WIMPs) by looking for nuclear recoils in the xenon target.
The current...

Weakly Interacting Massive Particles (WIMPs) are a class of yet to be discovered particles hypothesized to be components of the non-baryonic dark matter content of the universe. A blind analysis of 140.2 kg-days of data revealed three WIMP-candidate events with an expected total background of 0.7 events. These data favor a WIMP+background hypothesis over the known-background-only hypothesis at...

Results from a search for an annual modulation in 3.4 years of continuous, stable CoGeNT data-taking will be presented. The improved performance of the first C-4 detector will be discussed.

The MAJORANA DEMONSTRATOR is an array of natural and enriched high purity germanium detectors that will search for the neutrinoless double-beta decay of germanium-76 and perform a search for WIMPs with masses below 10 GeV. As part of the MAJORANA research and development efforts, we have deployed a modified, low-background broad energy germanium detector at the Kimballton Underground Research...

KIMS experiment has obtained 2.5 years of data for annual modulation studies. From the limits of annual modulation amplitudes, we have calculated new limits of WIMP-nucleon cross sections for the WIMP mass ranges of 10-1000 GeV for spin (in)dependent scatterings. These will be compared with the parameter space of the DAMA annual modulation analysis. We have re-measured the quenching factor for...
