Search for neutrinoless double beta decay in 124Sn

EPJ Web of Conferences, 2014
The mass and nature of neutrinos play an important role in theories beyond the standard model. The nuclear β decay and double beta decay can provide the information on absolute effective mass of the neutrinos, which would represent a major advance in our

EVIDENCE FOR NEUTRINOLESS DOUBLE BETA DECAY [PDF]

Modern Physics Letters A, 2001
The data of the Heidelberg–Moscow double beta decay experiment for the measuring period August 1990–May 2000 (54.9813 kg y or 723.44 molyears), published recently, are analyzed using the potential of the Bayesian method for low counting rates. First evidence for neutrinoless double beta decay is observed giving first evidence for lepton number ...

Scalar-induced neutrinoless double beta decay in SU(5)

Journal of High Energy Physics
We discuss the role of heavy scalar fields in mediating neutrinoless double beta decay (0νββ) within the SU(5) Grand Unified Theory framework, extended suitably to include neutrino mass.

New findings on neutrinoless double beta decay matrix elements using IBM-2 [PDF]

EPJ Web of Conferences
Although the study of double beta decay has come a long way since the beginning, there is still much to research. The recent discovery of the ab­sence of a short-range component in the light neutrino exchange mechanism of the nuclear matrix element (NME)

Double Beta Decay [PDF]

International Journal of Modern Physics: Conference Series, 2018
Double beta decay is a key process to reveal a fundamental property of neutrinos. If neutrinos are Majorana particles, that is they are equivalent to their antiparticles, neutrinoless double beta ([Formula: see text]) decay, [Formula: see text], would occur.

Majorana phases beyond neutrinoless double beta decay

Journal of High Energy Physics
The ν M SM is defined as the SM extended to include dimension-5 operators. In this model neutrino masses violate lepton number, and two parameters of the lepton mixing matrix, the Majorana phases, are yet to be constrained.

Two neutrino double-beta decay and effective axial-vector coupling constant

EPJ Web of Conferences, 2018
The theoretical and experimental study of the two-neutrino double-beta decay (2νββ-decay) is of crucial importance for reliable calculation of matrix elements governing the neutrinoless double-beta decay (0νββ-decay).

Macroscopic neutrinoless double beta decay: Long range quantum coherence

Nuclear Physics B
We re-introduce, in light of our modern understanding of neutrinos, the concept of “macroscopic neutrinoless double beta decay” (MDBD) for Majorana neutrinos.

Searching for beyond the Standard Model physics using the improved description of 100Mo $$2\nu \beta \beta $$ 2 ν β β decay spectral shape with CUPID-Mo

European Physical Journal C: Particles and Fields
The current experiments searching for neutrinoless double- $$\beta $$ β ( $$0\nu \beta \beta $$ 0 ν β β ) decay also collect large statistics of Standard Model allowed two-neutrino double- $$\beta $$ β ( $$2\nu \beta \beta $$ 2 ν β β ) decay events ...
