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 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 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 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 کاملNeutrinoless Double-Beta Decay
This paper introduces the neutrinoless double-beta decay the rarest nuclear weak process and describes the status of the research for this transition, both from the point of view of theoretical nuclear physics and in terms of the present and future experimental scenarios. Implications of this phenomenon on crucial aspects of particle physics are briefly discussed. The calculations of the nuclea...
