Higher Order Couplings in Magnetized Brane Models
Hiroyuki Abe, Kang-Sin Choi, Tatsuo Kobayashi +1
We compute three-point and higher order couplings in magnetized brane models. We show that higher order couplings are written as products of three-point couplings. This behavior is…
Three generation magnetized orbifold models
Hiroyuki Abe, Kang-Sin Choi, Tatsuo Kobayashi +1
We study three generation models in the four-dimensional spacetime, which can be derived from the ten-dimensional N=1 super Yang-Mills theory on the orbifold background with a non-…
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…
Intersecting Brane World from Type I Compactification
Kang-Sin Choi
We elaborate that general intersecting brane models on orbifolds are obtained from type I string compactifications and their T-duals. Symmetry breaking and restoration occur via re…
Unification in Intersecting Brane Models
Kang-Sin Choi
We propose a unification scenario for supersymmetric intersecting brane models. The quarks and leptons are embedded into adjoint representations of SO(32), which are obtained and b…
Dynkin diagram strategy for orbifolding with Wilson lines
Kang-Sin Choi, Kyuwan Hwang, Jihn E. Kim
A simple method for breaking gauge groups by orbifolding is presented. We extend the method of Kac and Peterson to include Wilson lines. The complete classification of the gauge gr…
