Nuclear-atomic state degeneracy in neutrinoless double-electron capture: A unique test for a Majorana-neutrino
There is a general consensus that detection of a double-beta decay without any neutrino involved would mark physics beyond the Standard Model. This is because in such decay modes lepton number conservation would be violated and the neutrino would reveal itself as being its own antiparticle. It is this particle-antiparticle duality which makes the neutrino of Majorana type. So far, the experimen...
متن کاملNeutrinoless double beta decay search with SNO+
The SNO+ experiment is the follow up of SNO. The detector is located 2 km underground in the Vale Canada Ltd.’s Creighton Mine near Sudbury, Ontario, Canada. The active volume of the detector consists of 780 tonnes of Linear Alkyl Benzene (LAB) in an acrylic vessel of 12 m diameter, surrounded by about 9500 PMTs. The main goal of the SNO+ experiment is the search for neutrinoless double beta de...
متن کاملSearches for neutrinoless resonant double electron captures at LNGS
Several experiments were performed during last years at underground (3600 m w.e.) Laboratori Nazionali del Gran Sasso (LNGS) of the INFN (Italy) to search for resonant 2ε0ν captures in Ru, Cd, Ce, Dy, Dy, W, Os, Pt with the help of HP Ge semiconductor detectors, and ZnWO4 and 106CdWO4 crystal scintillators. No evidence for r-2ε0ν decays was found, and only T1/2 limits were established in the ra...
متن کاملRecent advances in neutrinoless double beta decay search
Even after the discovery of neutrino flavour oscillations, based on data from atmospheric, solar, reactor, and accelerator experiments, many characteristics of the neutrino remain unknown. Only the neutrino square-mass differences and the mixing angle values have been estimated, while the value of each mass eigenstate still hasn’t. Its nature (massive Majorana or Dirac particle) is still escapi...
متن کاملNeutrinoless double beta decay
The status of the search for neutrinoless double beta decay is reviewed. The effort to reach the sensitivity needed to cover the effective Majorana neutrino mass corresponding to the degenerate and inverted mass hierarchy is described. Various issues concerning the theory (and phenomenology) of the relation between the 0νββ decay rate and the absolute neutrino mass scale are discussed, in parti...
