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 ...

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: AN EXTREME CHALLENGE
Acta Polytechnica, 2013 Neutrino-less Double Beta Decay is the only known way to possibly resolve the nature of neutrino mass. The chances to cover the mass region predicted by the inverted hierarchy require a step forward in detector capability. A possibility is to make use of

Scalar-mediated double beta decay and LHC [PDF]
, 2016 The decay rate of neutrinoless double beta decay could be dominated by short-range diagrams involving heavy scalar particles ("topology-II" diagrams). Examples are diagrams with diquarks, leptoquarks or charged scalars.

Neutrinoless double beta decay in the supersymmetric seesaw model [PDF]
, 2002 Inspired by the recent HEIDELBERG-MOSCOW double beta decay experiment, we discuss the neutrinoless double beta decay in the supersymmetric seesaw model. Our numerical analysis indicates that we can naturally explain the data of the observed neutrinoless ...

Neutrinoless double beta decay without Majorana neutrinos
Physics Letters B, 2021 It is firmly believed that a signal of neutrinoless double beta decay can confirm the Majorana nature of neutrinos. However, we remind another possibility that a Majorana neutrino mass induced after some neutrinoless double beta decay processes can be ...

Double Beta Decay: A Shell Model Approach
Physics, 2022 Studies of weak interaction in nuclei are important tools for testing different aspects of the fundamental symmetries of the Standard Model. Neutrinoless double beta decay offers an unique venue of investigating the possibility that neutrinos are ...

Investigation of light dark matter with 2 $$\beta $$ β decay experiments
European Physical Journal C: Particles and Fields, 2023 Nuclei that are unstable with respect to double beta decay are investigated in this work for a novel dark matter (DM) direct detection approach. In particular, the diagram responsible for the neutrinoless double beta decay can be considered for the ...

What can we learn from neutrinoless double beta decay experiments? [PDF]
, 2004 We assess how well next generation neutrinoless double beta decay and normal neutrino beta decay experiments can answer four fundamental questions. 1) If neutrinoless double beta decay searches do not detect a signal, and if the spectrum is known to be ...
