“…This shows that the relation between the particle physics part of 0νββ decay and neutrino masses and mixing is direct in the sense that m ee depends on parameters which define the neutrino mass matrix. Therefore, the observation of 0νββ decay can in principle provide valuable information about the type of neutrino mass spectrum (Bilenky et al, 2001;Murayama and Pena-Garay, 2004;, the absolute neutrino mass scale (Choubey and Rodejohann, 2005;Joaquim, 2003;Matsuda et al, 2001;, and the Majorana CP-violating phases (Barger and Whisnant, 1999;Branco et al, 2003c;Czakon et al, 2000;Pascoli et al, 2006).…”

Several topics on CP violation in the lepton sector are reviewed. A few theoretical aspects concerning neutrino masses, leptonic mixing, and CP violation will be covered, with special emphasis on seesaw models. A discussion is provided on observable effects which are manifest in the presence of CP violation, particularly, in neutrino oscillations and neutrinoless double beta decay processes, and their possible implications in collider experiments such as the LHC. The role that leptonic CP violation may have played in the generation of the baryon asymmetry of the Universe through the mechanism of leptogenesis is also discussed.

Observables sensitive to absolute neutrino masses: Constraints and correlations from world neutrino data

In the context of three-flavor neutrino mixing, we present a thorough study of the phenomenological constraints applicable to three observables sensitive to absolute neutrino masses: The effective neutrino mass in Tritium beta decay (m β ); the effective Majorana neutrino mass in neutrinoless double beta decay (m ββ ); and the sum of neutrino masses in cosmology (Σ). We discuss the correlations among these variables which arise from the combination of all the available neutrino oscillation data, in both normal and inverse neutrino mass hierarchy. We set upper limits on m β by combining updated results from the Mainz and Troitsk experiments. We also consider the latest results on m ββ from the Heidelberg-Moscow experiment, both with and without the lower bound claimed by such experiment. We derive upper limits on Σ from an updated combination of data from the Wilkinson Microwave Anisotropy Probe (WMAP) satellite and the 2 degrees Fields (2dF) Galaxy Redshifts Survey, with and without Lyman-α forest data from the Sloan Digital Sky Survey (SDSS), in models with a non-zero running of the spectral index of primordial inflationary perturbations. The results are discussed in terms of two-dimensional projections of the globally allowed region in the (m β , m ββ , Σ) parameter space, which neatly show the relative impact of each data set. In particular, the (in)compatibility between Σ and m ββ constraints is highlighted for various combinations of data. We also briefly discuss how future neutrino data (both oscillatory and non-oscillatory) can further probe the currently allowed regions. PACS numbers: 14.60.Pq,95.35.+d,

We present accurate predictions of the effective Majorana mass |m ββ | in neutrinoless double-β decay in the standard case of 3ν mixing and in the case of 3+1 neutrino mixing indicated by the reactor, Gallium and LSND anomalies. We have taken into account the uncertainties of the neutrino mixing parameters determined by oscillation experiments. It is shown that the predictions for |m ββ | in the cases of 3ν and 3+1 mixing are quite different, in agreement with previous discussions in the literature, and that future measurements of neutrinoless double-β decay and of the effective light neutrino mass in β decay or the total mass of the three lightest neutrinos in cosmological experiments may distinguish the 3ν and 3+1 cases if the mass ordering is determined by oscillation experiments. We also present a relatively simple method to determine the minimum value of |m ββ | in the general case of N -neutrino mixing.
