Confronting the scale-unifying model through νμ-ντ oscillations

It is observed that the recently proposed scale-unifying model based on the idea of supersymmetry and compositeness leads to rather restrictive predictions for neutrino masses and their mixings. One important prediction of the model is the prominence of νμ-ντ oscillations, which should certainly be observable in the proposed experiments. The relevance of the model to (a) the MSV explanation for the solar neutrino puzzle, (b) the recently reported 17 keV neutrino, (c) neutrinoless double beta decay and (d) deviations from universality in tau and muon decay is discussed.
