Gauge Model for Maximal Neutrino Mixing

Abstract

The recently announced Super-Kamiokande data on atmospheric neutrino oscillation seems to require a maximal mixing between the ${\nu }_{\mu }$ and ${\nu }_{\tau }$ within the conventional three neutrino picture. It is then tempting to suggest as has been done in literature, that the solar neutrino deficit be also understood as resulting from a maximal mixing between ${\nu }_e$ and ${\nu }_{\mu }$. In this letter, we propose a left-right symmetric extension of the standard model where permutation symmetry leads to one of the maximal mixing patterns in a technically natural manner. The double seesaw mechanism gives small Majorana masses for neutrinos needed to understand the atmospheric as well as the solar neutrino puzzles.
