Description
I will survey some aspects of geometric compactifications of heterotic
strings and their low-energy phenomenology. In particular, I will
focus on heterotic "non-standard embeddings". First, I will try to
give a brief overview over the role of vector bundles in that
construction, and how they can be constructed. Using our "heterotic
standard model", I will discuss how the spectrum and Yukawa textures
arise.
One observation is that not all possible superpotential terms are
actually present in such compactifications. For example, I will
consider a particular model with one excess Higgs-Higgs conjugate
pair. It turns out that flavor-changing neutral currents are greatly
suppressed.
