– 1 – Neutrinoless Double - Β Decay
Neutrinoless double-beta (0νββ) decay would signal violation of total lepton number conservation. The process can be mediated by an exchange of a light Majorana neutrino, or by an exchange of other particles. However, the existence of 0νββ decay requires Majorana neutrino mass, no matter what the actual mechanism is. As long as only a limit on the lifetime is available, limits on the effective ...
متن کاملNeutrinoless Double Β-decay 1
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 کاملNeutrino oscillations and neutrinoless double-β decay
We consider the scheme with mixing of three neutrinos and a mass hierarchy. We shown that, under the natural assumptions that massive neutrinos are Majorana particles and there are no unlikely fine-tuned cancellations among the contributions of the different neutrino masses, the results of solar neutrino experiments imply a lower bound for the effective Majorana mass in neutrinoless double-β de...
متن کاملThe neutrinoless double β decay and the neutrino mass hierarchy
Recently the evidence of the neutrinoless double β (0νββ) decay has been announced. This means that neutrinos are Majorana particles and their mass hierarchy is forced to certain patterns in the diagonal basis of charged lepton mass matrix. We estimate the magnitude of 0νββ decay in the classification of the neutrino mass hierarchy patterns as Type A, m1,2 ≪ m3, Type B, m1 ∼ m2 ≫ m3, and Type C...
متن کاملJastrow functions in double-β decay
We use simple analytic considerations and a Monte Carlo calculation of nucleons in a box to argue that the use of Jastrow functions as short-range correlators in the commonly employed two-body cluster approximation causes significant errors in the matrix elements for double-β decay. The Jastrow approach appears to agree with others, however, if many-body clusters are included. A careful treatme...
