G4: Neutrino: Neutrinoless Double-Beta Decays
- Yuriy Tikhonov (Budker Institute of Nuclear Physics, Novosibrsk, RF)
It is extremely important for future neutrinoless double-beta ($0\nu\beta\beta$) decay experiments to reach a sensitivity to effective Majorana neutrino mass $|m_{\beta\beta}|$~meV. At this level, the determination of neutrinos’ Majorana nature, absolute masses and the constraints on one of two Majorana CP phases are possible, which will provide profound insights into understanding the...
The discovery that neutrinos are Majorana fermions would have profound implications for particle physics and cosmology. The Majorana character of neutrinos would make neutrinoless double-beta ($0\nu\beta\beta$) decay, a matter-creating process without the balancing emission of antimatter, possible. The LEGEND Collaboration pursues a phased, $^{76}$Ge-based double-beta decay experimental...
Neutrinoless double beta decay search is a powerful tool to clarify the nature of neutrino as a Dirac or Majorana-type particle and probe the unknown neutrino mass.
Observing this decay means the lepton number violating process, which will help us understand the baryon asymmetric universe with the leptogenesis scenario.
The AMoRE collaboration has been searching for neutrinoless double...
Neutrinoless double-beta decay (0$\nu\beta\beta$) is a key process to address some of the major outstanding issues in particle physics, such as the lepton number conservation and the Majorana nature of the neutrino. Several efforts have taken place in the last decades in order to reach higher and higher sensitivity on its half-life. The next-generation of experiments aims at covering the...
The Cryogenic Underground Observatory for Rare Events (CUORE)
is the first bolometric experiment searching for 0νββ decay
that has successfully reached the one-tonne mass scale.
The detector, located at the LNGS in Italy, consists of an array of 988 TeO2 crystals arranged in a compact cylindrical structure of 19 towers.
CUORE began its first physics data run in 2017 at a base temperature...
We present a project to develop Gallium containing scintillator detector for low energy neutrino studies. GAGG(Ce) is a relatively new highly efficient fast inorganic scintillator. Recently the scintillator was propsed (P. Huber, 2022) as neutrino detector to test the well known and still not yet resolved Gallium anomaly. Following this idea we evaluate GAGG(Ce) scintillator as a possible...
