SUMMARY:Search for Neutrino-less Double Beta Decay with EXO-200\, NPAC
  (Nuclear/Particle/Astro/Cosmo) Forum\, Delia Tosi\, Stanford Universi
 ty
DESCRIPTION:Neutrino-less double beta decay may answer essential open 
 questions in neutrino physics. While double beta decay accompanied by 
 the emission of two neutrinos is allowed by the standard model\, the n
 eutrino-less process requires neutrinos to be Majorana particles. Dete
 cting this decay could determine the nature of neutrinos\, the neutrin
 o effective mass\, and the mass hierarchy.  The Enriched Xenon Observa
 tory (EXO) is an experimental program searching for neutrino-less doub
 le beta decay in xenon-136.  The first stage of this program\, EXO-200
 \, features 200 kg of liquid xenon.  The detector\, located at the Was
 te Isolation Pilot Plant in New Mexico\, has been taking data for two 
 years. EXO-200 detected for the first time two-neutrino double beta de
 cay of xenon\, the slowest process ever measured directly. Furthermore
  it set a strong limit on the rate of zero-neutrino double beta decay.
  I will describe EXO-200 as well as prospects for the future large-sca
 le detector nEXO.
