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,…
E8(8) in Light Cone Superspace
Lars Brink, Sung-Soo Kim, Pierre Ramond
We derive the non-linear action of E8(8) on the constrained chiral superfield in the light-cone superspace with eight complex Grassmann variables. We construct (to lowest order in…
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…
E_7(7) on the Light Cone
Lars Brink, Sung-Soo Kim, Pierre Ramond
We use the Cremmer-Julia E_7(7) non-linear symmetry of N=8 Supergravity to derive its order on-shell Hamiltonian in terms of one chiral light-cone superfield. By requiring th…
