Search for neutrinoless double-beta decay of Ge-76 with GERDA
Gerda, the GERmanium Detector Array experiment, is a new double beta-decay experiment which is currently under construction in the INFN National Gran Sasso Laboratory (Lngs), Italy. It is implementing a new shielding concept by operating bare Ge diodes enriched in Ge-76 in high purity liquid argon supplemented by a water shield. The aim of Gerda is to verify or refute the recent claim of discov...
متن کاملNeutrinoless double beta decay experiments
The study of neutrinoless double beta decay is of outmost importance for neutrino physics. It is considered to be the gold plated channel to probe the fundamental character of neutrinos and to determine the neutrino mass. From the experimental point about nine different isotopes are explored for the search. After a general introduction follows a short discussion on nuclear matrix element calcul...
متن کاملExperiments for Neutrinoless Double-Beta Decay
The recent neutrino oscillation experimental results indicate that at least one neutrino has a mass greater than 50 meV. The next generation of double-beta decay experiments will very likely have a sensitivity to an effective Majorana neutrino mass below this target. Therefore this is a very exciting time for this field of research as even null results from these experiments have the potential ...
متن کاملNeutrinoless ββ matrix element of 76 Ge from spectroscopic data
In this work we use the recently measured neutron pairing correlations in the 76 Ge and 76 Se nuclei as a guideline to adjust the single-particle energies in the 1p0f0g shell. The resulting BCS occupations reproduce the measured pairing data. The proton energies were inspected by using the odd-mass nuclei adjacent to 76 Ge and 76 Se as spectroscopic tools. The nuclear matrix element of the neut...
متن کاملAnalysis around Q ββ for 76 Ge Double Beta Decay experiments , and Statistics at Low Count Rates
The background in the region of the Q-value for neutrinoless double beta decay of Ge has been investigated by different methods: Simulation with GEANT 4 of the HEIDELBERG-MOSCOW experiment, analysis of other Ge double beta experiments. Statistical features of the analysis at very low count rates are discussed.
