The search for Majorana neutrinos with a background-free gaseous Xenon TPC at the tonne scale. (February 2020) - Monrabal, F.
Abstract: The next generation of neutrinoless double beta decay search experiments aims to reach sensitivities to this half-life of the process up to 10 28 years. This will require tonne scale detectors with almost no background in their region of interest, which represents a large improvement with respect to current technologies. With this scenario, the NEXT collaboration presents two parallel developments: NEXT- High Definition and NEXT- Barium atOm Light Detection. The first is based on the incremental improvement of the current pressure gas xenon technology, and the second is based on the use of a barium tagging technology.
