Anomaly Conditions for Non-Abelian Finite Family Symmetries
Christoph Luhn, Pierre Ramond
Assuming that finite family symmetries are gauged, we derive discrete anomaly conditions for various non-Abelian groups. We thus provide new constraints for flavor model building,…
Quintics with Finite Simple Symmetries
Christoph Luhn, Pierre Ramond
We construct all quintic invariants in five variables with simple Non-Abelian finite symmetry groups. These define Calabi-Yau three-folds which are left invariant by the action of…
Simple Finite Non-Abelian Flavor Groups
Christoph Luhn, Salah Nasri, Pierre Ramond
The recently measured unexpected neutrino mixing patterns have caused a resurgence of interest in the study of finite flavor groups with two- and three-dimensional irreducible repr…
Proton Hexality from an Anomalous Flavor U(1) and Neutrino Masses - Linking to the String Scale
Herbi K. Dreiner, Christoph Luhn, Hitoshi Murayama +1
We devise minimalistic gauged U(1)_X Froggatt-Nielsen models which at low-energy give rise to the recently suggested discrete gauge Z_6 symmetry, proton hexality, thus stabilizing…
Tri-Bimaximal Neutrino Mixing and the Family Symmetry Z_7 x Z_3
Christoph Luhn, Salah Nasri, Pierre Ramond
The Non-Abelian finite group PSL_2(7) is the only simple subgroup of SU(3) with a complex three-dimensional irreducible representation. It has two maximal subgroups, S_4 which, alo…
The Flavor Group Delta(3n^2)
Christoph Luhn, Salah Nasri, Pierre Ramond
The large neutrino mixing angles have generated interest in finite subgroups of SU(3), as clues towards understanding the flavor structure of the Standard Model. In this work, we s…
