Neutrino Mass Spectrum and Future Beta Decay Experiments
We study the discovery potential of future beta decay experiments on searches for the neutrino mass in the sub-eV range, and, in particular, KATRIN experiment with sensitivity m > 0.3 eV. Effects of neutrino mass and mixing on the beta decay spectrum in the neutrino schemes which explain the solar and atmospheric neutrino data are discussed. The schemes which lead to observable effects contain ...
متن کاملNeutrino Mass Patterns and Future Double-Beta Decay Experiments
The next generation of double-beta decay experiments have an excellent chance of providing data on the neutrino mass pattern. This presentation is a summary of what is currently known about the mass pattern and expectations from experiment. Uncertainties due to the precision in the oscillation parameters are not critical to the interpretation of a ββ(0ν) measurement in terms of the mass pattern...
متن کاملStatistical Analysis of future Neutrino Mass Experiments including Neutrino-less Double Beta Decay
We perform a statistical analysis with the prospective results of future experiments on neutrino-less double beta decay, direct searches for neutrino mass (KATRIN) and cosmological observations. Realistic errors are used and the nuclear matrix element uncertainty for neutrinoless double beta decay is also taken into account. Three benchmark scenarios are introduced, corresponding to quasi-degen...
متن کاملOn the Neutrino Mass Spectrum and Neutrinoless Double - Beta Decay
Assuming 3-ν mixing, neutrino oscillation explanation of the solar and atmospheric neutrino data and of the first KamLAND results, massive Majorana neutrinos and neutrinoless double-beta ((ββ) 0ν-) decay generated only by the (V-A) charged current weak interaction via the exchange of the three Majorana neutrinos, we analyze in detail the possibility of determining the type of the neutrino mass ...
متن کاملNeutrino Mass Spectrum and Neutrinoless Double Beta Decay
The relations between the effective Majorana mass of the electron neutrino, mee, responsible for neutrinoless double beta decay, and the neutrino oscillation parameters are considered. We show that for any specific oscillation pattern mee can take any value (from zero to the existing upper bound) for normal mass hierarchy and it can have a minimum for inverse hierarchy. This means that oscillat...
