Description
The observation of neutrinoless double beta decay will confirm the Majorana
nature of neutrinos and it will provide first evidence of lepton number violation. The NEMO-3 experiment took data from 2003 to 2011, with Mo-100 and Se-82 as main sources. The SuperNEMO experiment improves on the NEMO-3 technique by increasing the mass of the source, improving the energy resolution and the detector efficiency, and by reducing backgrounds. The SuperNEMO experiment, using a tracker-calorimeter technique, will be able to measure the full kinematic signature of the decays, which is an important condition for studying the underlying physics mechanism of neutrinoless double beta decay. The SuperNEMO demonstrator module is currently under construction, with data taking due to begin next year.
The latest results from NEMO-3 will be summarised, and the current status of the SuperNEMO experiment will be presented.
