The 27 representation of E6 and neutrino physics — •Christophe Cauet1, Thomas Kephart2, Heinrich Päs1, and Ivo de Medeiros Varzielas1 — 1Institut für Physik, TU Dortmund, 44221 Dortmund, Germany — 2Vanderbilt University, 6301 Stevenson Center, Nashville, TN 37235, USA
A successful grand unified theory has to explain neutrino masses and mixing naturally, without the need for additional conditions. We present a systematic approach to classify models based on the exceptional group E6, e.g. [SU(3)]3 trinification, and show possible mechanism to generate neutrino masses in the 0.1 eV region.
