Research Abstract |
We have studied four-dimensional low-energy effective field theory, derived from superstring theory, in particular heterotic string theory on the orbifolds and magnetized/intersecting brane models. We have studied Abelian and non-Abelian discrete symmetries, which appear in these string models. Also we have studied their anomalies and found that the universal relations among certain anomalies. Furthermore, by explicit string computations we have shown stringy coupling selection rules, which seem to be difficult to understand from the symmetries of low-energy effective field theories.
