Three-parameter Lorentz-violating texture for neutrino mixing

Global three-parameter model for neutrino oscillations using Lorentz violation

A model of neutrino oscillations is presented that has only three degrees of freedom and is consistent with existing data. The model is a subset of the renormalizable sector of the Standard-Model Extension (SME), and it offers an alternative to the standard three-neutrino massive model. All classes of neutrino data are described, including solar, reactor, atmospheric, and LSND oscillations. The...

Two–mixing Texture for Three Active Neutrinos *

The conjecture that among three massive neutrinos ν1 , ν2 , ν3 there is no direct mixing between ν1 and ν3 leads to a two–mixing texture for three active neutrinos νe , νμ , ντ . This texture, much discussed previously, is neatly consistent with the observed deficits of solar νe’s and atmospheric νμ’s, but (without extra mixing with at least one sterile neutrino νs) predicts no LSND effect for ...

Neutrino masses and sneutrino mixing in R-parity violating supersymmetry∗†

R-parity-violating supersymmetry with a conserved baryon number B provides a framework for particle physics with lepton number (L) violating interactions. Two important probes of the L-violating physics are neutrino masses and sneutrino-antisneutrino mass-splittings. We evaluate these quantities in the context of the most general CP-conserving, R-parity-violating B-conserving extension of the m...
