The Absolute

At least one neutrino has a mass of about 50 meV or larger. However, the absolute mass scale for the neutrino remains unknown. Studies of double beta decay offer hope for determining the absolute mass scale. Furthermore, the critical question "Is the neutrino its own antiparticle?" is unanswered. In particular, zero-neutrino double beta decay (0 νββ) can address the issues of lepton number conservation, the particle–antiparticle nature of the neutrino, and its mass. A summary of the recent progress in 0 νββ, and the related technologies will be discussed in the context of the future 0 νββ program.

We study the existence of one/two texture zeros or one/two vanishing minors in the neutrino mass matrix with μτ symmetry. In the basis where the charged lepton mass matrix and the Dirac neutrino mass matrix are diagonal, the one/two zeros or one/two vanishing minors on the right-handed Majorana mass matrix having μτ symmetry will propagate via seesaw mechanism as one/two vanishing minors or one/two texture zeros in the neutrino mass matrix with μτ symmetry respectively. It is found that only five such texture structures of the neutrino mass matrix are phenomenologically viable. For tribimaximal mixing, these texture structures reduce the number of free parameters to one. Interesting predictions are obtained for the effective Majorana mass Mee, the absolute mass scale and the Majorana-type CP violating phases.

Recent years have witnessed many exciting breakthroughs in neutrino physics. The detection of neutrino oscillations has proved that neutrinos are massive particles, but the assessment of their absolute mass scale is still an outstanding challenge in today particle physics and cosmology. Since low temperature detectors were first proposed for neutrino physics experiments in 1984, there has been tremendous technical progress: today this technique offers the high energy resolution and scalability required to perform competitive experiments challenging the lowest electron neutrino masses. This paper reviews the thirty-year effort aimed at realizing calorimetric measurements with sub-eV neutrino mass sensitivity using low temperature detectors.

Practical Tool

Neutrinoless double beta decay (ββ(0ν)) is presently the only practical tool for probing the character of neutrinos. In case neutrinos are Majorana particles ββ(0ν) can provide also fundamental informations on their absolute mass scale. The present status of experiments searching for ββ(0ν) is reviewed and the most relevant results discussed. A possibility to observe ββ(0ν) at a neutrino mass scale in the range 10-50 meV looks possible according to our present knowledge of the neutrino masses and mixing parameters. A review of the future projects and of the most relevant parameters contributing to the experimental sensitivity iss finally outlined.
