Flavored Orbifold GUT - an SO(10) x S4 model

Understand

Orbifold grand unified theories (GUTs) solve several problems in GUT model building.

• Therefore, it is intriguing to investigate similar constructions in the flavor context.
• In this paper, we propose that a flavor symmetry might emerge due to orbifold compactification of one orbifold and broken by boundary conditions of another orbifold.
• The combination of the orbifold parities in gauge and flavor space determines the zero modes.
