Gerda
GERDA, the GERmanium Detector Array, is a particle-physics experiment at the Gran Sasso National Laboratory in Italy designed to search for neutrinoless double beta decay of the isotope 76Ge. The observation of such decay would indicate that neutrinos are Majorana particles and would have implications for the neutrino mass scale and lepton number conservation.
GERDA uses large, enrichment-grade germanium detectors made from 76Ge, operated as bare diodes submerged in liquid
Phase I (2011–2013) achieved low background and set a stringent lower limit on the half-life for neutrinoless
GERDA’s work contributed significantly to the development of the LEGEND project, which aims to scale up germanium-based
By providing some of the most stringent constraints on neutrinoless double beta decay in 76Ge, GERDA has
