Non-Abelian Discrete Flavor Symmetries from Magnetized/Intersecting Brane Models
Hiroyuki Abe, Kang-Sin Choi, Tatsuo Kobayashi +1
We study non-abelian discrete flavor symmetries, which can appear in magnetized brane models. For example, , and can appear and matter fields with several repr…
Contorted Flavors in Grand Unification and Proton Decay
Kang-Sin Choi
Conventionally we collect electron and up/down-quarks (u,d)+(nu_e,e) to form unified generations, and collect the left-handed and the right-handed fermions of the same flavors (nu_…
Discrete R-symmetry anomalies in heterotic orbifold models
Takeshi Araki, Kang-Sin Choi, Tatsuo Kobayashi +2
Anomalies of discrete R-symmetries appearing in heterotic orbifold models are studied. We find that the mixed anomalies for different gauge groups satisfy the universal Green-Schwa…
Three family orbifold trinification, MSSM and doublet-triplet splitting problem
Kang-Sin Choi, Jihn E. Kim
A orbifold compactification of heterotic string is considered toward a trinification with three light families. The GUT scale VEV's of the $S…
Softening of SUSY flavor problem from asymptotically free bulk interactions
Kang-Sin Choi, Ki-Young Choi, Jihn E. Kim
Recently, it was pointed out that soft masses of the supersymmetric gauge theories with extra dimensions tends to a flavor conserving point, which is a desirable scenario in gravit…
