Neutrinoless double-beta decay, which is a very old and yet elusive process, is reviewed. Its
observation will signal that the lepton number is not conserved and that the neutrinos are …

The observation of neutrinoless double beta decay (DBD) will have important
consequences. First it will signal that lepton number is not conserved and the neutrinos are …

Weak-interaction and nuclear-structure aspects of double beta decay are reviewed. Starting
from effective electroweak lagrangians, decay rates for the two-neutrino and neutrinoless …

Neutrinoless double beta decay is a very important process both from the particle and
nuclear physics point of view. From the elementary particle point of view it pops up in almost …

In this work we perform a systematic study of pairs of single-β-decaying nuclei in the mass
region A= 100–136 to extract information on the effective value of the axial-vector coupling …

A compilation of data on double beta decay is presented. The tables contain the most
stringent known experimental limits or positive results on half-lives for 2β transitions to …

A systematic study of the two-neutrino double beta (2νββ) decay to the final ground state and
excited states is performed within an extension of the quasiparticle random-phase …

The renormalized proton-neutron quasiparticle random-phase approximation model
(RQRPA) has been used to calculate double-β-decay matrix elements and associated …

In this work we investigate general properties of the nuclear matrix elements (NMEs) related
to the neutrinoless double β− decays (0νβ− β− decays) of several nuclei of interest for …

We review the recent work done by the Jyväskylä–La Plata collaboration on the calculation
of nuclear matrix elements for various modes of double-beta decays. Whenever helpful, we …
