✦ Synopsis
We show that an improved sensitivity on effective neutrino mass to the atmospheric neutrino mass scale with the next generation germanium-based double-beta decay experiment together with results from cosmology survey, θ 13 measurements and neutrino oscillation experiments may be able to determine the absolute mass scale of the neutrino, and answer the question of the neutrino nature. To achieve such a sensitivity of 45 meV, the next generation germanium experiment must reduce background by a factor of 440 comparing to the existing results. The planned germanium experiment at the Deep Underground Science and Engineering Laboratory (DUSEL) in western South Dakota aims at achieving such a sensitivity. Sanford Lab supported by the state of South Dakota and a private donor, Mr. T. Denny Sanford, will be up and running within the next year to pave the way for the creation of DUSEL in five years.
