Neutrinos and Trinification — •Christophe Cauet¹, Heinrich Päs¹, and Sören Wiesenfeldt² — ¹Institut für Physik, TU Dortmund, 44221 Dortmund, Germany — ²Institut für Theoretische Teilchenphysik, Universität Karlsruhe, 76128 Karlsruhe, Germany

We revisit the minimal SU(3)_C× SU(3)_L× SU(3)_R×Z₃ Trinification model proposed by J. Sayre, S. Wiesenfeldt and S. Willenbrock in 2006. While the model predicts proton decay rates above the experimental limits and incorporates successful gauge coupling unification without the need for supersymmetry, it predicts small mixing for solar neutrinos, which has been ruled out by the KamLAND experiment. The scenario is updated in view of recent neutrino data and phenomenological consequences are discussed.
