Non-Abelian discrete flavor symmetries from magnetized/intersecting brane models

Abstract

We study non-Abelian discrete flavor symmetries, which appear in magnetized brane models. For example, D 4 , Δ ( 27 ) and Δ ( 54 ) flavor symmetries can appear with matter fields in several representations. We also study the orbifold background, where non-Abelian flavor symmetries are broken in a certain way.
