Search for double beta decay of 116 Cd with enriched 116
The Aurora experiment to investigate double beta decay of Cd with the help of 1.162 kg cadmium tungstate crystal scintillators enriched in Cd to 82% is in progress at the Gran Sasso Underground Laboratory. The half-life of Cd relatively to the two neutrino double beta decay is measured with the highest up-to-date accuracy T1/2 = (2.62 ± 0.14) × 10 yr. The sensitivity of the experiment to the ne...
متن کاملCharacterization of a ZnSe scintillating bolometer prototype for neutrinoless double beta decay search
As proposed in the LUCIFER project, ZnSe crystals are attractive materials to realize scintillating bolometers aiming at the search for neutrinoless double beta decay of the promising isotope 82Se. However, the optimization of the ZnSe-based detectors is rather complex and requires a wide-range investigation of the crystal features: optical properties, crystalline quality, scintillation yields ...
متن کاملFirst Evidence for Neutrinoless Double Beta Decay
Double beta decay is indispensable to solve the question of the neutrino mass matrix together with ν oscillation experiments. Recent analysis of the most sensitive experiment since nine years the HEIDELBERG-MOSCOW experiment in Gran-Sasso yields a first indication for the neutrinoless decay mode. This result is the first evidence for lepton number violation and proves the neutrino to be a Major...
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...
متن کاملThe Potential of Hybrid Pixel Detectors in the Search for the Neutrinoless Double-Beta Decay of Cd-116
We investigated the potential of the energy resolving hybrid pixel detector Timepix contacted to a CdTe sensor layer for the search for the neutrinoless double-beta decay of 116Cd. We found that a CdTe sensor layer with 3mm thickness and 165 μm pixel pitch is optimal with respect to the effective Majorana neutrino mass (m ββ ) sensitivity. In simulations, we were able to demonstrate a possible ...
