Towards absolute neutrino masses
Various ways of determining the absolute neutrino masses are briefly reviewed and their sensitivities compared. The apparent tension between the announced but unconfirmed observation of the 0νββ decay and the neutrino mass upper limit based on observational cosmology is used as an example of what could happen eventually. The possibility of a “nonstandard” mechanism of the 0νββ decay is stressed...
متن کاملAbsolute Neutrino Masses
where U is the mixing matrix (see Refs. [1–3]). Neutrino oscillations depend on the elements of the mixing matrix U , which determine the amplitude of the oscillations, and on the squared-mass differences ∆m2kj ≡ m 2 k − m 2 j , which determine the oscillation length. The results of solar neutrino experiments (Homestake [4], Kamiokande [5], SAGE [6], GALLEX [7], GNO [8], Super-Kamiokande [9] an...
متن کاملPhenomenology of Absolute Neutrino Masses
Solar, atmospheric and long-baseline neutrino oscillation experiments obtained convincing evidence that neutrinos are massive and mixed particles. Since on one hand solar and KamLAND experiments and on the other hand atmospheric and K2K experiments are sensitive to oscillations generated by different orders of magnitude of differences of squared neutrino masses, at least two independent ∆m SUN ...
متن کاملAbsolute Values of Neutrino Masses: Status and Prospects
Compelling evidences in favor of neutrino masses and mixing obtained in the last years in Super-Kamiokande, SNO, KamLAND and other neutrino experiments made the physics of massive and mixed neutrinos a frontier field of research in particle physics and astrophysics. There are many open problems in this new field. In this review we consider the problem of the absolute values of neutrino masses, ...
متن کاملFlavor Mixing, Quark Masses, Neutrino Masses and Neutrino Oscillations
We discuss first the flavor mixing of the quarks, using the texture zero mass matrices. Then we study a similar model for the mass matrices of the leptons. We are able to relate the mass eigenvalues of the charged leptons and of the neutrinos to the mixing angles and can predict the masses of the neutrinos. We find a normal hierarchy the masses are 0.004 eV, 0.01 eV and 0.05 eV. The atmospheric...
