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.
