Workshop on Calculation of Double-Beta-Decay Matrix Elements (MEDEX '07)

All papers have been peer-reviewed. The determination of the properties of the neutrino is one of the most pursued goals of physics. The relevance of the neutrino mass problem, for fields so closely related as astro-particle physics, elementary particle physics, cosmology and nuclear structure physics, becomes evident after the discovery of the neutrino oscillations. The series of MEDEX Conferences, which started ten years ago, is devoted to the update of the experimental and theoretical information related to the nuclear double beta decay, which is the process that may, if observed, be the tool to answer the fundamental questions related to the neutrino mass scale. MEDEX is established as a unique forum for theoreticians and experimentalists which are active in the field. The major experimental collaborations have reported regularly at MEDEX since the first meeting 1997.

The conference is devoted to the discussion of new theoretical and experimental results on the field of double beta decay processes. The interplay between theoretical and experimental results is crucial in order to determine the magnitude of the electron-neutrino mass and its properties.
