Ab initio uncertainty quantification of neutrinoless double-beta decay in 76Ge [PDF]

Physical Review Letters, 2023
The observation of neutrinoless double-beta (0νββ) decay would offer proof of lepton number violation, demonstrating that neutrinos are Majorana particles, while also helping us understand why there is more matter than antimatter in the Universe.

Determination of Double Beta Decay Half-Life of ¹³⁶Xe with the PandaX-4T Natural Xenon Detector. [PDF]

Research (Wash D C), 2022
Precise measurement of two-neutrino double beta decay (DBD) half-life is an important step for the searches of Majorana neutrinos with neutrinoless double beta decay. We report the measurement of DBD half-life of 136Xe using the PandaX-4T dual-phase Time

Challenges in Double Beta Decay [PDF]

Advances in High Energy Physics, 2014
In the past ten years, neutrino oscillation experiments have provided the incontrovertible evidence that neutrinos mix and have finite masses. These results represent the strongest demonstration that the electroweak Standard Model is incomplete

Neutrinoless double beta decay

New Journal of Physics, 2015
We review the potential to probe new physics with neutrinoless double beta decay $(A,Z)\to (A,Z+2)+2{e}^{-}.$ Both the standard long-range light neutrino mechanism as well as non-standard long-range and short-range mechanisms mediated by heavy particles ...

Searching for New Physics in Two-Neutrino Double Beta Decay [PDF]

Physical Review Letters, 2020
Motivated by nonzero neutrino masses and the possibility of new physics discovery, a number of experiments search for neutrinoless double beta decay. While hunting for this hypothetical nuclear process, a significant amount of two-neutrino double beta ...

Barium Chemosensors with Dry-Phase Fluorescence for Neutrinoless Double Beta Decay. [PDF]

Sci Rep, 2019
The nature of the neutrino is one of the major open questions in experimental nuclear and particle physics. The most sensitive known method to establish the Majorana nature of the neutrino is detection of the ultra-rare process of neutrinoless double ...

On neutrinoless double beta decay in the νMSM

Physics Letters B, 2016
We consider the neutrinoless double beta (0νββ) decay in the νMSM, in which three right-handed neutrinos with masses below the electroweak scale are additionally introduced to the Standard Model. In this model there appear three heavy neutral leptons N1,
