The eclectic flavor symmetries of orbifolds
Alexander Baur, Hans Peter Nilles, Saul Ramos-Sanchez +2
Only four orbifold building blocks are admissible in heterotic string compactifications. We investigate the flavor properties of all of these building b…
Top-Down Anatomy of Flavor Symmetry Breakdown
Alexander Baur, Hans Peter Nilles, Saul Ramos-Sanchez +2
A top-down approach to the flavor puzzle leads to eclectic flavor groups which include modular and traditional flavor symmetries. Based on examples of semirealistic T2/Z3 orbifold…
Completing the eclectic flavor scheme of the orbifold
Alexander Baur, Moritz Kade, Hans Peter Nilles +2
We present a detailed analysis of the eclectic flavor structure of the two-dimensional orbifold with its two unconstrained moduli and as well as $\mathrm{SL}(…
Siegel modular flavor group and CP from string theory
Alexander Baur, Moritz Kade, Hans Peter Nilles +2
We derive the potential modular symmetries of heterotic string theory. For a toroidal compactification with Wilson line modulus, we obtain the Siegel modular group $\mathrm{Sp}(4,\…
The eclectic flavor symmetry of the orbifold
Alexander Baur, Moritz Kade, Hans Peter Nilles +2
Modular symmetries naturally combine with traditional flavor symmetries and , giving rise to the so-called eclectic flavor symmetry. We apply this scheme to the two-d…
A String Theory of Flavor and CP
Alexander Baur, Hans Peter Nilles, Andreas Trautner +1
Modular transformations of string theory (including the well-known stringy dualities) play a crucial role in the discussion of discrete flavor symmetries in the Standard Model. The…
Unification of Flavor, CP, and Modular Symmetries
Alexander Baur, Hans Peter Nilles, Andreas Trautner +1
Flavor symmetry plays a crucial role in the standard model of particle physics but its origin is still unknown. We develop a new method (based on outer automorphisms of the Narain…
