The objective of R&D R2D2 is to develop a very simple TPC filled with pressurized xenon for the search of neutrinoless double beta decays (2β0ν). We tested several chamber concepts - spherical (SPC) or cylindrical (CPC) geometries - with an argon-methane gas mixture at pressures up to 8 bars. We report the results obtained in ionization and proportional modes, especially in terms of signal...
Neutrinoless double-beta (0ν2β) decay is physics beyond the Standard Model. If discovered, it would demonstrate that neutrinos are their own antiparticles, a property known as Majorana nature.
KamLAND-Zen is a project to search for the 0ν2β decay of 136Xe. It uses an organic liquid scintillator with dissolved xenon gas as both the source and detector. The experimental apparatus is located...

The PandaX-III experiment aims to detect the Neutrinoless Double-beta decay (NLDBD), a hypothetical process where only two electrons are emitted from the atomic nucleus. Since the Q-value of the decay is divided only...
