The discovery of neutrinoless β β decay could soon be within reach. This hypothetical
ultrarare nuclear decay offers a privileged portal to physics beyond the standard model of …

Neutrinoless double-beta decay is a forbidden, lepton-number-violating nuclear transition
whose observation would have fundamental implications for neutrino physics, theories …

We present an improved search for neutrinoless double-beta (0 ν β β) decay of Xe 136 in the
KamLAND-Zen experiment. Owing to purification of the xenon-loaded liquid scintillator, we …

The KamLAND-Zen experiment has provided stringent constraints on the neutrinoless
double-beta (0 ν β β) decay half-life in Xe 136 using a xenon-loaded liquid scintillator. We …

The nuclear matrix elements that govern the rate of neutrinoless double beta decay must be
accurately calculated if experiments are to reach their full potential. Theorists have been …

The possibility that neutrinos may be their own antiparticles, unique among the known
fundamental particles, arises from the symmetric theory of fermions proposed by Ettore …

We report new results from the search for neutrinoless double-beta decay in Te 130 with the
CUORE detector. This search benefits from a fourfold increase in exposure, lower trigger …

The discovery of neutrino masses through the observation of oscillations boosted the
importance of neutrinoless double beta decay (0νββ). In this paper, we review the main …

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 …
