The Cadmium Zinc Telluride 0-Neutrino Double-Beta(COBRA) experiment is a large array of Cadmium Zinc Telluride(CZT) semiconductors currently being utilized to search for evidence of the neutrino-less double beta decay, and to measure it's half life, this should act as a probe to physics beyond The Standard Model as well as finding the neutrino mass. It is located within the Gran Sasso National Laboratory (LNGS). Papers on this method have been published since 2001 and installation of a large prototype began in 2006.

Set upEdit
The COBRA experiment is currently in the research & development stages, in order to prove the validity of the proposed techniques. The initial set up of the experiment was an array of four
ResultsEdit
COBRA has collected about 200 kg days of calibrated exposure, these data are being analysed in order to understand the background factors and to determine half life limits for isotopes of interest. Current efforts are focused on reducing the background readings in order to increase the sensitivity of the experiment. Another potential solution is to use liquid scintillators as a low-noise background for the detectors, which has been proven possible in other experiments.
