SUMMARY:Recent Results from the Cogent Dark Matter Search\, NPAC (Nucl
 ear/Particle/Astro/Cosmo) Forum\, Mike Miller\, University of Washingt
 on\, CENPA
DESCRIPTION:Dark Matter is one of the grand questions of our era.  Com
 posing up to 25% of our universe\, its cosmological impacts and gravit
 ational evidence appear robust.   Not surprisingly\, the search for di
 rect detection via a non-gravitational force is now a massive enterpri
 se.  Only one experiment (DAMA/LIBRA) has claimed direct detection in 
 the lab by searching for the hypothesized annual rate modulation of th
 e Dark Matter Halo model.  CoGeNT is a table top experiment that lever
 ages novel advances in kilogram-scale germanium detectors\, thus enabl
 ing the study of extremely low-energy ionization events.  Armed with t
 he world's lowest energy threshold\, CoGeNT set forth to rule out some
  of DAMA's final hiding places only to be surprised by a statistically
 -limited annual modulation signal beyond that of known backgrounds.  W
 hile far from a discovery of dark matter\, the CoGeNT results raise im
 portant and exciting questions.  We will present the latest results fr
 om CoGeNT and plans for the future.
