An Anisotropic Orbifold Compactification of the Heterotic String — •Jonas Schmidt — DESY Hamburg, Notkestrasse 85, D-22603 Hamburg

We study an anisotropic limit of the Z_6−II orbifold compactification model of the E₈ × E₈ heterotic string first described in hep-ph/0511035. This model is known to give the correct MSSM matter content at low energies without further exotics. The introduction of a hierarchy between the radii of compactification of the three appearing two-tori can naturally explain the discrepancy between the GUT and the Planck scale. We present a resulting effective six dimensional Orbifold GUT theory with SU(6) gauge symmetry in the bulk in the visible sector. All fields in this model are fixed by the embedding into the heterotic string. The resulting spectrum is anomaly-free and preserves the wanted four dimensional low-energy properties.
