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 …

The theoretical and experimental issues relevant to neutrinoless double beta decay are
reviewed. The impact that a direct observation of this exotic process would have on …

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 …

We review recent studies of the evolution of collective excitations in atomic nuclei far from
the valley of β-stability. Collective degrees of freedom govern essential aspects of nuclear …

We have examined the importance of momentum-dependent-induced nucleon currents such
as weak-magnetism and pseudoscalar couplings to the amplitude of neutrinoless double …

We review the recent developments in the field of nuclear double beta decay, which is
presently an important topic in both nuclear and particle physics. The mechanism of lepton …

In the present study we generalize the self-consistent Hartree-Fock-Bogoliubov (HFB) theory
formulated in the coordinate space to the case which incorporates an arbitrary mixing …

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 …

We have investigated the role of proton-neutron pairing in the context of the quasiparticle
random phase approximation formalism. This way the neutrinoless double beta decay matrix …
