Neutrino mass matrix solutions and neutrinoless double beta decay
We present a determination of the neutrino mass matrix which holds for values of the neutrinoless double beta decay effective mass mee larger than the neutrino mass differences. We find eight possible solutions and discuss for each one the corresponding neutrino mass eigenvalues and zero texture. A minimal structure of the perturbations to add to these zero textures to recover the full mass mat...
متن کاملNeutrinoless Double Beta Decay - and the Neutrino Mass Matrix
Double beta decay is indispensable to solve the question of the neutrino mass matrix together with ν oscillation experiments. Recent analysis of the most sensitive experiment since eight years the HEIDELBERG-MOSCOW experiment in Gran-Sasso yields evidence for the neutrinoless decay mode. This result is the first evidence for lepton number violation and proves the neutrino to be a Majorana parti...
متن کاملNeutrino Mass, Bulk Majoron and Neutrinoless Double Beta Decay
A new economical model for neutrino masses is proposed in the context of the brane-bulk scenarios for particle physics, where the global B−L symmetry of the standard model is broken spontaneously by a gauge singlet Higgs field in the bulk. This leads to a bulk singlet majoron whose Kaluza-Klein excitations may make it visible in neutrinoless double beta decay for some parameter range if the str...
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...
