Neutrinoless double beta decay search with the GERDA experiment
The Gerda experiment, located at the Laboratori Nazionali del Gran Sasso (LNGS), searches for the neutrinoless double beta decay of 76Ge. The experiment is using 36 kg of high-purity germanium detectors, simultaneously as source and detector, deployed into ultra-pure cryogenic liquid argon. Gerda is one the leading experiments in the field, reporting the highest sensitivity on the half-life of 0νββ decay with 1.1 · 1026 yr, the lowest background index with 6 · 10 −4 cts/(keV·kg·yr) and an excellent energy resolution of 0.12% (FWHM). The experimental setup, the analysis procedures and the latest results of Gerda are summarized in the present work.
期刊介绍：
La Rivista del Nuovo Cimento is an international peer-reviewed journal. It publishes monographs in all fields of physics. These monographies aim at presenting the state of the art of topical subjects of relevant interest for the community. Usually, authors are invited and topics suggested by the Deputy Editors-in-Chief, but also spontaneous submissions are examined.
