Search for neutrinoless double-beta decay of Ge-76 with GERDA
نویسنده
چکیده
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 discovery, and, in a second phase, to achieve a two orders of magnitude lower background index than recent experiments. The paper discusses motivation, physics reach, design and status of construction of Gerda, and presents some R&D results.

The progress in the development of the new international Gerda (GErmanium Detector Array) experiment is presented. Main purpose of the experiment is to search for the neutrinoless double beta decay of Ge. The experimental set up is under construction in the underground laboratory of LNGS. Gerda will operate with bare germanium semiconductor detectors (enriched in Ge) situated in liquid argon. I...
متن کاملSearch for neutrinoless double beta decay of 76Ge with the GERmanium Detector Array "GERDA"
The study of neutrinoless double beta decay (DBD) is the only one presently known approach to the fundamental question if the neutrino is a Majorana particle, i.e. its own anti-particle. The observation of neutrinoless DBD would not only establish the Majorana nature of the neutrino but also represent a determination of its effective mass if the nuclear matrix element is given. So far, the most...

Neutrinoless double-beta (0νββ) decay is practically the only way to establish the Majorana nature of the neutrino mass and its decay rate provides a probe of an effective neutrino mass. Double beta experiments are long-running underground experiments with specific challenges concerning the background reduction and the long term stability. These problems are addressed in this work for the Heide...

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.
متن کاملStatus Report of the GERDA Phase II Startup
The GERmanium Detector Array (GERDA) experiment, located at the Laboratori Nazionali del Gran Sasso (LNGS) of INFN, searches for 0νββ of Ge. Germanium diodes enriched to ∼ 86 % in the double beta emitter Ge(Ge) are exposed being both source and detectors of 0νββ decay. Neutrinoless double beta decay is considered a powerful probe to address still open issues in the neutrino sector of the (beyon...
