The Majorana neutrino masses, neutrinoless double beta decay and nuclear matrix elements
The effective Majorana neutrino mass mββ is evaluated by using the latest results of neutrino oscillation experiments. The problems of the neutrino mass spectrum, absolute mass scale of neutrinos and the effect of CP phases are addressed. A connection to the next generation of the neutrinoless double beta decay (0νββ-decay) experiments is discussed. The calculations are performed for Ge, Mo, Xe...
متن کاملNeutrinoless double beta decay
The status of the search for neutrinoless double beta decay is reviewed. The effort to reach the sensitivity needed to cover the effective Majorana neutrino mass corresponding to the degenerate and inverted mass hierarchy is described. Various issues concerning the theory (and phenomenology) of the relation between the 0νββ decay rate and the absolute neutrino mass scale are discussed, in parti...
متن کاملNeutrinoless Double-Beta Decay
This paper introduces the neutrinoless double-beta decay the rarest nuclear weak process and describes the status of the research for this transition, both from the point of view of theoretical nuclear physics and in terms of the present and future experimental scenarios. Implications of this phenomenon on crucial aspects of particle physics are briefly discussed. The calculations of the nuclea...
متن کاملOn Nuclear Matrix Element Uncertainties in Short Range 0νββ Decay Neutrinoless Double Beta Decay
The evaluation of short range contributions to neutrinoless double beta decay has been challenged due to critics of the ansatz of the nuclear matrix element calculations. We comment on the critics and uncertainties of these calculations and the effect on the derived limits. A Z+2 X + 2e − (1) has been proven to be one of the most sensitive tools to search for particle physics beyond the standar...
متن کاملPionic Matrix Elements in Neutrinoless Double-β Decay
Physics beyond the standard model of electroweak interactions that violates lepton number will, in general, induce operators involving the quark and lepton fields that violate lepton number. I point out that some matrix elements of particular operators are known. In the limit of exact SU(3) flavor symmetry the operator uγμ(1−γ5)d uγμ(1−γ5)d is part of the 27 representation responsible for ∆ I =...
