Non-abelian brane worlds: the heterotic string story
We discuss chiral supersymmetric compactifications of the SO(32) heterotic string on Calabi-Yau manifolds equipped with direct sums of stable bundles with structure group U( n ). In addition we allow for non-perturbative heterotic five-branes. These models are S-dual to type I compactifications with...

| Zusammenfassung: | We discuss chiral supersymmetric compactifications of the SO(32) heterotic string on Calabi-Yau manifolds equipped with direct sums of stable bundles with structure group U( n ). In addition we allow for non-perturbative heterotic five-branes. These models are S-dual to type I compactifications with D9- and D5-branes, which by themselves are mirror symmetric to general intersecting D6-brane models. For the construction of concrete examples we consider elliptically fibered Calabi-Yau manifolds with SU( n ) bundles given by the spectral cover construction. The U( n ) bundles are obtained via twisting by line bundles. We present a four-generation Pati-Salam and a three-generation Standard-like model. |
