Neutrino oscillations in low density medium

A. N. Ioannisian, A. Yu. Smirnov

For the case of small matter effects: $V ≪ Δ m^{2} /2 E$ , where $V$ is the matter potential, we develop the perturbation theory using $ε \equiv 2 V E /Δ m^{2}$ as the expansion parameter. We…

Neutrino masses and mixing: Singular mass matrices and Quark-lepton symmetry

I. Dorsner, A. Yu. Smirnov

We suggest an approach to explain the observed pattern of the neutrino masses and mixing which employs the weakly broken quark-lepton symmetry and does not require introduction of…
