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 …

Neutrino–nuclear responses associated with astro-neutrinos, single beta decays and double
beta decays are crucial in studies of neutrino properties of interest for astro-particle physics …

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 …

In this review the quenching of the weak axial-vector coupling strength, g A, is discussed in
nuclear β and double-β decays. On one hand, the nuclear-medium and nuclear many-body …

Background: Direct determination of the neutrino mass through double-β decay is at the
present time one of the most important areas of experimental and theoretical research in …

We present a formalism for calculating nuclear matrix elements of double-β decay within the
framework of the microscopic interacting boson model. We calculate Fermi, Gamow-Teller …

We review recent developments in double-beta decay, focusing on what can be learned
about the three light neutrinos in future experiments. We examine the effects of uncertainties …

This paper introduces the neutrinoless double‐beta decay (the rarest nuclear weak process)
and describes the status of the research for this transition, both from the point of view of …

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 …

Abstract Ground-state-to-ground-state two-neutrino double beta (2 ν β β) decays and single
beta (EC and β−) decays are studied for the A= 100 (100 Mosingle bond 100 Tcsingle bond …
