Model-independent Constraint on the Neutrino Mass Spectrum from the Neutrinoless Double Beta Decay
نویسنده
چکیده
We present a concise formula to relate the effective mass term of the neutrinoless double beta decay to a single neutrino mass, two Majorana CP-violating phases and four observables of neutrino oscillations for a generic neutrino mass spectrum. If the alleged evidence for the neutrinoless double beta decay is taken into account, one may obtain a rough but model-independent constraint on the absolute scale of neutrino masses – it is most likely to be in the range between 0.1 eV and 1 eV.

Neutrinoless Double Beta Decay and New Physics in the Neutrino Sector
Neutrinoless double beta decay belongs to the most sensitive tools for the search of new physics beyond the standard model. The recent half life limit of the Heidelberg–Moscow experiment implies restrictive bounds on the absolute mass scale in the neutrino sector. Possible improvements by the GENIUS project provide a unique possibility to reconstruct the neutrino mass spectrum. Further constrai...
متن کاملWhat can we learn from neutrinoless double beta decay experiments?
We assess how well next-generation neutrinoless double beta decay and normal neutrino beta decay experiments can answer four fundamental questions. ~1! If neutrinoless double beta decay searches do not detect a signal, and if the spectrum is known to be inverted hierarchy, can we conclude that neutrinos are Dirac particles? ~2! If neutrinoless double beta decay searches are negative and a next-...
متن کاملMajorana neutrino masses from neutrinoless double beta decay and cosmology
When three Majorana neutrinos describe the solar and atmospheric neutrino data via oscillations, a nonzero measurement of neutrinoless double beta (0νββ) decay can determine the sum of neutrino masses ∑ mν if the solar solution has small-angle mixing, and place a lower bound on ∑ mν for large-angle solar mixing. If in addition a nonzero ∑ mν is deduced from cosmology, the neutrino mass spectrum...

The neutrinoless double β-decay is reviewed. Model independent evidence in favor of neutrino masses and mixing is briefly summarized. The data of the recent experiments on the search for 0νββ-decay are presented and some future experiments are discussed. The possible values of the effective Majorana mass, which can be predicted on the basis of the neutrino oscillation data under different assum...
متن کاملNeutrinoless Double Beta Decay in Theories Beyond the Standard Model
Neutrinoless double beta decay pops up almost in any extension of the standard model. It is perhaps the only process, which can unambiguously determine whether the massive neutrinos are Majorana or Dirac type particles. In addition from the lifetime of this decay, combined with sufficient knowledge of the relevant nuclear matrix elements, one can set a constraint involving the neutrino masses. ...
