Phenomenology of Absolute Neutrino Masses
نویسنده
چکیده
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 ≪ ∆m ATM are needed in order to explain the data. This requirement is satisfied by the simplest three-neutrino mixing scheme in which the left-handed components ναL of flavor neutrinos (α = e, μ, τ) are linear combinations of the left-handed components νkL of massive neutrinos (k = 1, 2, 3): ναL = ∑

Theory and Phenomenology of Neutrino Mixing
We review some fundamental aspects of the theory of neutrino masses and mixing. The results of neutrino oscillation experiments are interpreted as evidence of three-neutrino mixing. Implications for the mixing parameters and the neutrino masses are discussed, with emphasis on the connection with the measurements of the absolute values of neutrino masses in beta decay and neutrinoless double-bet...
متن کاملPhenomenology of a New Supersymmetric Standard Model: The μνSSM
The μνSSM solves the μ problem of the MSSM and explains the origin of neutrino masses by simply using right-handed neutrino superfields. The solution implies the breaking of R-parity. The properties and phenomenology of the model are briefly reviewed.
متن کاملNeutrino Phenomenology – the case of two right handed neutrinos
We make a general analysis of neutrino phenomenology for the case neutrino masses are generated by the see-saw mechanism with just two right handed neutrinos. We find general constraints on leptogenesis and lepton flavour violating processes. We also analyse the predictions following from a nontrivial texture
