The connection of neutrino physics with the neutrinoless double-beta decay is reviewed. After presenting the current status of the Pontecorvo–Maki–Nakagawa–Sakata matrix and the theoretical background of neutrino mass and lepton mixing, we will summarize the various implications of neutrino physics for the double-beta decay. The influence of light sterile neutrinos and other exotic modifications of the three neutrino picture is also discussed. 
Light sterile neutrinos and neutrinoless double-beta decay
The LSND, Gallium and reactor neutrino anomalies can be explained by short-baseline neutrino oscillations due to the mixing of the active neutrinos with sterile neutrinos at the eV scale. I review
Neutrinoless Double Beta Decay
We review the potential to probe new physics with neutrinoless double beta decay ( A , Z ) → ( A , Z + 2 ) + 2 e − . ?> Both the standard long-range light neutrino mechanism as well as non-standard
Neutrinoless Double-Beta Decay: a Probe of Physics Beyond the Standard Model
In the Standard Model the total lepton number is conserved. Thus, neutrinoless double-beta decay, in which the total lepton number is violated by two units, is a probe of physics beyond the Standard
Neutrinoless Double Beta Decay: 2015 Review
The discovery of neutrino masses through the observation of oscillations boosted the importance of neutrinoless double beta decay (). In this paper, we review the main features of this process,
Predictions for Neutrinoless Double-Beta Decay in the 3+1 Sterile Neutrino Scenario
In this proceeding we present predictions of the effective Majorana mass |mββ| in neutrinoless double-β decay for the standard 3v mixing case and for the 3+1 neutrino mixing case indicated by the
Update of Short-Baseline Electron Neutrino and Antineutrino Disappearance
We present a complete update of the analysis of electron neutrino and antineutrino disappearance experiments in terms of neutrino oscillations in the framework of 3+1 neutrino mixing, taking into
We present an overview on some basic properties of massive neutrinos and focus on their flavor issues, including the mass spectrum, flavor mixing pattern and CP violation. The lepton flavor

We review the status of light sterile neutrino searches, motivated by the original Short BaseLine (SBL) anomalies. Here, we discuss how sterile neutrino properties can be constrained by different


CP violation in neutrinoless double beta decay and neutrino oscillation
Taking account of possible CP violation, we discuss about the constraints on the lepton mixing angles from the neutrinoless double beta decay and from the neutrino oscillation for the three flavour
We review the particle physics aspects of neutrino-less double beta decay. This process can be mediated by light massive Majorana neutrinos (standard interpretation) or by something else
Constraining mass spectra with sterile neutrinos from neutrinoless double beta decay, tritium beta decay and cosmology
We analyze the constraints on neutrino mass spectra with extra sterile neutrinos as implied by the LSND experiment. The various mass related observables in neutrinoless double beta decay, tritium
Double Beta Decay, Majorana Neutrinos, and Neutrino Mass
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 elementary particle physics,

We perform a statistical analysis with the prospective results of future experiments on neutrino-less double beta decay, direct searches for neutrino mass (KATRIN) and cosmological observations.
Neutrino Parameter Space for a Vanishing ee Element in the Neutrino Mass Matrix
The consequences of a texture zero at the ee entry of neutrino mass matrix in the flavor basis, which also implies a vanishing effective Majorana mass for neutrinoless double beta decay, have been
