Signal of neutrinoless double beta decay, neutrino spectrum and oscillation scenarios.

摘要: The lower and upper bounds on the neutrinoless double beta (0ν2β) decay rate are obtained, as functions of parameters neutrino oscillations lightest mass. constraints these from search for 0ν2β transition, well interpretation solar atmospheric data in terms oscillations, can be conveniently represented one unitarity triangle. This representation helps to clarify cases when is small; crucial dependence scenarios assumed spectrum emphasized. We consider hierarchical non-hierarchical spectra, discuss their interest view future searches decay.
