Orbifolds versus smooth heterotic compactifications
Abstract
Description
Following the recent exploration of smooth heterotic compactifications with unitary bundles, orbifold compactifications in six dimensions can be shown to correspond in the blow-up to compactifications with U(1) gauge backgrounds. A powerful tool is the comparison of anomaly polynomials. The presentation here focuses on heterotic SO(32) compactifications in six dimensions including five-branes. Four dimensional and E8 x E8 models are briefly commented on.
