The Majorana nature of neutrinos is strongly motivated from the theoretical and
phenomenological point of view. A plethora of neutrino mass models, known collectively as …

A plausible explanation for the lightness of neutrino masses is that neutrinos are massless at
tree level, with their mass (typically Majorana) being generated radiatively at one or more …

The GERmanium Detector Array (GERDA) experiment searched for the lepton-number-
violating neutrinoless double-β (0 ν β β) decay of Ge 76, whose discovery would have far …

The GERDA experiment searches for the lepton-number-violating neutrinoless double-β
decay of Ge 76 (Ge 76→ Se 76+ 2 e-) operating bare Ge diodes with an enriched Ge 76 …

The CUORE experiment, a ton-scale cryogenic bolometer array, recently began operation at
the Laboratori Nazionali del Gran Sasso in Italy. The array represents a significant …

The observation of neutrinoless double-beta decay (0νββ) would show that lepton number is
violated, reveal that neu-trinos are Majorana particles, and provide information on neutrino …

A discovery that neutrinos are Majorana fermions would have profound implications for
particle physics and cosmology. The Majorana character of neutrinos would make possible …

The ordering of the neutrino masses is a crucial input for a deep understanding of flavor
physics, and its determination may provide the key to establish the relationship among the …

Results from a search for neutrinoless double-beta decay (0 ν β β) of Xe 136 are presented
using the first year of data taken with the upgraded EXO-200 detector. Relative to previous …

The Majorana Collaboration is operating an array of high purity Ge detectors to search for
neutrinoless double-β decay in Ge 76. The Majorana Demonstrator comprises 44.1 kg of Ge …
