The search for zero neutrino double beta decay in 136-Xe with EXO-200
Abstract/Contents
- Abstract
- This analysis reports a search for the neutrinoless double decay (0[nu][beta][beta]) of 136-Xe with the EXO-200 detector. 0[nu][beta][beta] is a hypothetical nuclear process which only occurs if neutrinos are so called Majorana particles, which are there own anti-particles, as opposed to Dirac particles which have separate anti-particles. The search for 0[nu][beta][beta] is currently the most experimentally viable technique to address the Dirac or Majorana nature of neutrinos. The EXO-200 experiment is a liquid xenon time projection cham- ber operating 655 meters underground at the Waste Isolation Pilot Plant (WIPP) with 200 kg of xenon enriched to 80.6% in the isotope 136-Xe. A total of one event in the one sigma region of interest is observed with background of (1.5 ± .1) × 10^−3 counts/keV/kg/yr. This places a limit on the 0[nu][beta][beta] half-life of 136Xe is of 1.59×10^25.
