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_…

Higher Order Couplings from Heterotic Orbifold Theory
Kang-Sin Choi, Tatsuo Kobayashi
We calculate couplings of arbitrary order from correlation functions among twisted strings, using conformal field theory. Twisted strings arise in heterotic string compactified on…

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…
